- Cu(II) complexes of hydrazones–NSAID conjugates: synthesis, characterization and anticancer activity
-
The hydrazones of nonsteroidal anti-inflammatory drugs (NSAIDs) diclofenac and ibuprofen are synthesized with aldehydes of pyridine and imidazole and are characterized by 1H, 13C and mass spectroscopy. Cu(II) complexes of hydrazones constructed from these ligands possess square planar geometry for bidentate diclofenac-hydrazone and tridentate ibuprofen-hydrazone conjugates with [Cu(L)2] and [Cu(L)Cl] compositions, respectively. The observed irreversible Cu(II)/Cu(I) redox couple in the range of +0.20 to +0.61 V is due to the substantial distortion in the square-planar geometry. ESR studies indicate the appreciably covalent character within M–L bonding due to extensive delocalization of electron from d x2–-y2 orbital. The hydrazone–NSAID conjugates exhibit substantial cytotoxicity against A-549, HCT-116 and MDA-MB-231 cancer cell lines with ibuprofen-imidazole-hydrazone ligand possessing the lowest IC50 (2.26 μM) amongst the synthesized NSAID-conjugates. Interestingly, its Cu(II) complex also displays excellent anticancer activity against MDA-MB- 231 with IC50 value of 3.58 μM. Such a feature may be ascribed to the synergistic association of Cu(II)–NSAID–hydrazone linkage. Thus, conjugation of NSAID with hydrazone and its complexation with a bioactive metal ion may be regarded as a potential strategy for designing of non-platinum anticancer agents.

- A new ibuprofen derivative inhibits platelet aggregation and ros mediated platelet apoptosis
-
Thrombocytopenia is a serious issue connected with the pathogenesis of several human diseases including chronic inflammation, arthritis, Alzheimer's disease, cardiovascular diseases (CVDs) and other oxidative stress-associated pathologies. The indiscriminate use of antibiotics and other biological drugs are reported to result in thrombocytopenia, which is often neglected during the treatment regime. In addition, augmented oxidative stress induced by drugs and pathological conditions has also been shown to induce thrombocytopenia, which seems to be the most obvious consequence of elevated rate of platelet apoptosis. Thus, blocking oxidative stress-induced platelet apoptosis would be of prime importance in order to negotiate thrombocytopenia and associated human pathologies. The current study presents the synthesis and platelet protective nature of novel ibuprofen derivatives. The potent anti-oxidant ibuprofen derivative 4f was selected for the study and the platelet protective efficacy and platelet aggregation inhibitory property has been demonstrated. The compound 4f dose dependently mitigates the oxidative stress-induced platelet apoptosis in both platelet rich plasma and washed platelets. The platelet protective nature of compound 4f was determined by assessing various apoptotic markers such as ROS generation, cytosolic Ca2+levels, PS externalization, cytochrome C translocation, Caspase activation, mitochondrial membrane depolarization, cytotoxicity, LDH leakage and tyrosine phosphorylation of cytosolic proteins. Furthermore, compound 4f dose dependently ameliorated agonist induced platelet aggregation. Therefore, compound 4f can be estimated as a potential candidate in the treatment regime of pathological disorders associated with platelet activation and apoptosis. In addition, compound 4f can be used as an auxiliary therapeutic agent in pathologies associated with thrombocytopenia.

- Phenyl substituted thiazole linked 1, 2, 4-triazole derivatives: Synthesis and their biological evaluation
-
Synthesize and evaluate some phenyl substituted thiazole linked 1, 2, 4-triazole derivatives as antimicrobial agents. Compounds containing 1, 2, 4-triazole moieties are widely used as antimicrobial and antifungal agents whereas thiazole is another heterocyclic ring exhibiting various pharmacological actions. It is interesting to incorporate different bioactive pharmacophores in the same molecular framework to examine cumulative effect exerted by the moiety. This hypothesis was applied in research work by having triazole and thiazole in the same molecular framework. The present work was mainly focused on synthesis of some 1, 2, 4-triazole derivatives linking with phenyl substituted thiazole nucleus and their evaluation for biological activity. The compounds (8a-8j) were synthesized as per design scheme and elucidated their structures using different spectroscopic data of IR, 1HNMR, 13CNMR & mass spectroscopy. These synthesized derivatives were evaluated for their antibacterial activity using broth dilution assay. Further, mechanism of action of test compounds was examined using protein leakage assay. All the spectral data were confirmed the synthesis of phenyl substituted thiazole linked 1, 2, 4-triazole derivatives and some of them exhibited significant antimicrobial activity. Amongst all compound 8c showed most potent activity with lowest IC50 values 180 μg/ml and 120 μg/ml against S. aureus & amp; B. cereus respectively. Whereas compound 8j demonstrated strong inhibitory activities only against negative strains P. aeruginosa and E. coli with lowest IC50 values 240 μg/mL and 200μg/mL respectively.

- Carbonic anhydrase inhibitory potential of 1,2,4-triazole-3-thione derivatives of flurbiprofen, ibuprofen and 4-tert-butylbenzoic hydrazide: Design, synthesis, characterization, biochemical evaluation, molecular docking and dynamic simulation studies
-
Background: The over-expression of the carbonic anhydrases results in some specific carcinomas including pancreatic, gastric and brain tumor. Tumors are distinguished under hypoxic conditions and various investigations are being carried out to target the known hypoxic areas of the tumors to increase the sensitivity towards standard therapeutic treatment. Objective: Herein, we have designed and synthesized some biologically important esters, hydrazides, thiocarbamates, 1,2,4-triazole-3-thiones and Schiff bases. The purpose of the research was to evaluate the derivative against carbonic anhydrase and to assess the toxicity of the same compounds. Method: The structures of all the compounds were characterized by FT-IR, mass spectrometry, elemental analysis, 1H and 13C NMR spectroscopy. The synthetic derivatives were screened for their inhibitory potential against carbonic anhydrase II by in vitro assay. Double reciprocal plots for inhibition kinetics of the potent compounds were constructed and mode of inhibition was determined. Furthermore, to check the cytotoxicity, these derivatives were tested against human breast adenocarcinoma by MTT method. Results: X-ray diffraction analysis of the compounds 10, 14 and 15 showed that they did not have any φ-φ or C-H…φ interactions. The experimental results were validated by molecular docking and dynamic simulations of the potent compounds in the active pocket of enzyme. Important binding interactions of potent compounds with the key residues in the active site of the carbonic anhydrase enzyme were revealed. Drug likeness profile of the derivatives was evaluated to determine the physicochemical properties. Conclusion: The proposed synthetic approach provides a suitable platform for the generation of a new library of compounds which could potentially be employed in the future testing and optimization of inhibitor potencies.

- Synthesis and Biological Evaluation of New Ibuprofen-1,3,4-oxadiazole-1,2,3-triazole Hybrids
-
A new hybrid polydentate template comprising distinctive pharmacophoric groups, namely, ibuprofen, 1,3,4-oxadiazole, and 1,2,3-triazole linked through a thioether bridge was achieved by one-pot synthesis by exploring multicomponent Cu-catalyzed “click chemistry” approach. The target structures were characterized by NMR, IR, and LC-Mass. The X-ray analysis of 2-(1-(4-isobutylphenyl)ethyl)-5-(((1-(3-nitrophenyl)-1H-1,2,3-triazol-4-yl)methyl)thio)-1,3,4-oxadiazole (8a) confirmed the assigned structure. The in vitro antibacterial and anticancer activity of these compounds revealed that 2-(1-(4-isobutylphenyl)ethyl)-5-(((1-phenyl-1H-1,2,3-triazol-4-yl)methyl)thio)-1,3,4-oxadiazole (8b) demonstrated more potent antibacterial activity against Gram-negative strains (Escherichia coli and Pseudomonas aeruginosa) and 2-(((1-(2,4-dimethylphenyl)-1H-1,2,3-triazol-4-yl)methyl)thio)-5-(1-(4 isobutylphenyl)ethyl)-1,3,4-oxadiazole (8e) exhibited anticancer activity with IC50 of 27.50 and 31.03?μg/mL against HeLa and MCF-7 cell lines, respectively.

- Synthesis, characterization, and biological evaluation of furoxan coupled ibuprofen derivatives as anti-inflammatory agents
-
A series of furoxan-based nitric oxide releasing ibuprofen derivatives were synthesized and tested for their anti-inflammatory, analgesic, ulcerogenic, lipid peroxidation, and hepatotoxic properties. The compounds exhibited more protection than ibuprofen with regard to gastric toxicity. Among the tested compounds 4-[2-[2-(4-isobutylphenyl)propanamido]ethoxycarbonyl]-3-methylfuroxan and 4-[2-[2-(4-isobutylphenyl)propanoyl]hydrazinecarbonyl]-3-phenylfuroxan emerged as most active anti-inflammatory agents with reduced gastrotoxicity. The results showed that incorporation of NO donating group caused a moderate increase in anti-inflammatory activity with a marked decrease in gastric ulcerations compared to their parent drug ibuprofen. A molecular docking study of all the compounds was also performed to provide the binding modes of COX-1 enzyme. Among all the titled compounds, 4-[2-[2-(4-isobutylphenyl)propanamido]ethoxycarbonyl]-3-methylfuroxan was found to be most potent and have high docking score showing favorable orientation within the COX-1 binding site.

- Novel 1,3,4-oxadiazole/oxime hybrids: Synthesis, docking studies and investigation of anti-inflammatory, ulcerogenic liability and analgesic activities
-
A novel group of 1,3,4-oxadaiazoles, a group known for their anti-inflammatory activity, is hybridized with nitric oxide (NO) releasing group, oxime, for its gastro-protective action and potential synergistic effect. The synthesized hybrids were evaluated for their anti-inflammatory, analgesic, antioxidant and ulcerogenic activities. Most of the tested compounds showed excellent anti-inflammatory activity with compound 8e being more active than indomethacin. They also showed moderate analgesic activity but no antioxidant one. The ability of the synthesized compounds to inhibit COX-1 and COX-2 is studied and the prepared compounds were able to inhibit both COXs non-selectively with IC50s of 0.75–70.50?μM. Docking studies revealed the mode of interaction of the tested compounds into the empty pocket of the isozymes. All of the synthesized compounds interact with COXs active site with energy scores comparable to that of ibuprofen. All compounds showed a safer profile on the stomach tissue integrity compared to conventional NSAIDs. The designed strategy was applied to ibuprofen to introduce ibuprofen/oxadiazole/NO hybrid. The synthesized ibuprofen hybrid is a promising alternative to ibuprofen having similar anti-inflammatory activity but with safer GIT profile.

Using novel hybrid molecules for the treatment of tuberculosis is one of the latest approaches. Keeping this concept in mind, thirty two hybrid compounds were synthesized, with pyrrole as one of the moieties, clubbed to coumarin, ibuprofen and isoniazid. The compounds were evaluated against Mycobacterium tuberculosis H37Rv strain. Compounds 7e and 8e exhibited MIC of 3.7 and 5.10 μg mL-1 and growth inhibition of 95% and 92%, respectively. These compounds were also active against single drug resistant bacterial strains. The compounds were devoid of cytotoxicity when tested against Vero African green monkey kidney cell line. Docking study was carried out on enoyl acyl carrier protein enzyme to provide some understanding into the mechanism of action of these compounds.

Acyl / sulfonyl hydrazines were synthesized in a one-pot reaction from carboxylic acid/aryl sulfonic acid in the presence of 1,1′-carbonyl diimidazole (CDI) under ultrasound as well as under conventional heating. The reaction was performed on diverse organic molecules including simple benzoic acid (1), electron-donating and electron-withdrawing substituted benzoic acids, biologically active compounds like coumarin-3-carboxylic acid (12), 7-hydroxycoumarin-4-acetic acid (13), and therapeutic drugs like ibuprofen (14), flurbiprofen (15), naproxen (16) or tricyclic adamantane carboxylic acid (17). Benzene sulfonic acid (18) and its derivatives (19, 20, 21 and 22) were used to prepare corresponding sulfonyl hydrazide. All products were synthesized in very good yield via ultrasonic irradiation method and characterized by spectroscopic techniques including EIMS, 1H NMR, 13C NMR, IR. The method was found very simple, facile, efficient and high yielding (>90).

- Synthesis and biological evaluation of new 1,3-Thiazolidine-4-one Derivatives of 2-(4-Isobutylphenyl)propionic Acid
-
New thiazolidine-4-one derivatives of 2-(4-isobutylphenyl)propionic acid (ibuprofen) have been synthesized as potential anti-inflammatory drugs. The structure of the new compounds was proved using spectral methods (FR-IR, 1H-NMR, 13C-NMR, MS). The in vitro antioxidant potential of the synthesized compounds was evaluated according to the total antioxidant activity, the DPPH and ABTS radical scavenging assays. Reactive oxygen species (ROS) and free radicals are considered to be involved in many pathological events like diabetes mellitus, neurodegenerative diseases, cancer, infections and more recently, in inflammation. It is known that overproduction of free radicals may initiate and amplify the inflammatory process via upregulation of genes involved in the production of proinflammatory cytokines and adhesion molecules. The chemical modulation of acyl hydrazones of ibuprofen 3a-l through cyclization to the corresponding thiazolidine-4-ones 4a-n led to increased antioxidant potential, as all thiazolidine-4-ones were more active than their parent acyl hydrazones and also ibuprofen. The most active compounds are the thiazolidine-4-ones 4e, m, which showed the highest DPPH radical scavenging ability, their activity being comparable with vitamin E.

- N-2-Hydroxybenzaldehyde acylhydrazone-Fe(iii) complex: Synthesis, crystal structure and its efficient and selective N-methylation
-
N-Methyl-N′-2-hydroxybenzaldehyde acylhydrazones have been chemospecifically synthesized in good yield by N-methylation of the Fe(iii) complexes of N-2-hydroxybenzaldehyde acylhydrazones with methyl iodide in tetrahydrofuran. The reaction proceeds with the exclusive formation of the N-methyl derivative without any concurrent O-methylation side reactions. In addition, the N-methylation reaction occurred simultaneously with a complete deprotection step (elimination of the metal ion). As a result, the N-methyl product was obtained in excellent purity without time-consuming chromatographic workup. A free N-2-hydroxybenzaldehyde acylhydrazone ligand could not be methylated under the same conditions. This journal is the Partner Organisations 2014.

The neurotoxicity were assessed using the rotorod method. All the test compounds were administered at doses of 30, 100, and 300 mg/kg body weight and the anticonvulsant activity was noted at 0.5 and 4 h time intervals after the drug administration. Among the compound tested, all except 5g showed protection from seizures in both the animal models. Some titled compounds exhibited lesser CNS depression and neurotoxicity compared to phenytoin. A series of substituted hydrazide derivatives were synthesized, evaluated for their anticonvulsant potency in two animal models along with behavioural and neurotoxicity screen and also subjected to computational parameters.

- Design & synthesis of 2-(substituted aryloxy)-5-(substituted benzylidene)-3-phenyl-2,5-dihydro-1H-[1,2,4] triazin-6-one as potential anticonvulsant agents
-
A series of 2-(substituted aryloxy)-5-(substituted benzylidene)-3-phenyl-2, 5-dihydro-1H-[1,2,4] triazin-6-one were designed & synthesized using appropriate synthetic route keeping in view the structural requirement of pharmacophore and evaluated for anticonvulsant activity and CNS activities. After intraperitoneal injection to mice, some synthesized derivatives were examined in the maximal electroshock seizure (MES) and subcutaneous pentylenetetrazol (scPTZ) induced seizure and neurotoxicity screens. Those found potent were also evaluated for behavioural impairment and depression activity. Among the compound tested, 5 eIX showed protection from seizures in both the animal models at dose level of 30 mg/kg while 5 bII & 5 cII showed protection against scPTZ model at same dose level. Some titled compounds exhibited lesser CNS depression and neurotoxicity compared to clinically effective drug. A series of substituted [1,2,4] triazin-6-one derivatives were synthesized, evaluated for their anticonvulsant potency on two animal models along with CNS activity and neurotoxicity and also subjected to computational parameter.

- Prodrugs and mutual prodrugs: Synthesis of some new pyrazolone and oxadiazole analogues of a few non-steroidal anti-inflammatory drugs
-
Naproxen, probenecid, diclofenac, ibuprofen and indomethacin were converted to hydrazide derivatives via their methyl ester by reacting with hydrazine hydrate, which were further condensed with β-keto esters to get the pyrazolone derivatives. The hydrazide derivatives of probenecid and diclofenac were also reacted with biphenyl acetic acid while naproxen hydrazide was reacted with p-chloro benzoic acid besides biphenyl acetic acid to synthesize their oxadiazole analogues. Some selected members of the compounds prepared were screened for their anti-inflammatory and analgesic activity.
