Synthesis and biological evaluation of 2,4-disubstituted thiazole amide derivatives as anticancer agent

A series of novel 2,4-disubstituted thiazole amide derivatives were synthesized, and their antiproliferative activities were tested. Some of these compounds displayed good antiproliferative activity, especially for HT29 cell. Among these compounds, compound 5b inhibits A549, HeLa, HT29 and Karpas299 cells with IC50 values of 8.64, 6.05, 0.63 and 13.87?μM, respectively. The western blot analysis and docking study provide important clues for further optimization of compound 5b as a potential c-Met inhibitor.

Synthesis and biological screening of diethyl [N-(thiazol-2-yl)carbamoyl]methylphosphonates

A three-step synthesis, involving condensation of bromomethyl aryl ketones with urea to afford 2- aminothiazoles, their chloroacetylation and subsequent solvent-free Arbuzov phosphonation has afforded a series of novel diethyl [N-(thiazol-2-yl)carbamoyl]methylphosphonates 3a-3f in good overall yields; the 4- carboxythiazole analogue 3g was obtained by selective hydrolysis of the corresponding ethyl ester 3f. The phosphonate esters exhibited significant anti-cancer activity (nM - low μM IC50 values) against SH-SY5Y cells and, in one case, 7.6 μM MIC90 anti-TB activity against the virulent M. tuberculosis H37Rv strain; the chloroacetamido precursors all exhibited some antimalarial (PfLDH) activity, three with IC50 values in the range 1.0 - 8.9 μM.

Β - secretase enzyme has the function of inhibiting compound, the preparation of the compounds and use thereof

The invention discloses a compound capable of inhibiting beta-secretase, and a preparation method and application thereof. The structure of the compound is shown in a formula I, formula II or formula III as described in the specification. In the formula I, X is S or NH; R1 is selected from hydrogen and nitro group; R2 and R4 are same or different and independently selected from the group consisting of hydrogen, halogen, nitro group and substituted aryl group; R3 is selected from the group consisting of hydrogen, nitro group, straight-chain and branched-chain alkyl and substituted alkyl groups with a carbon number of 1 to 4, alkylamino or alkyloxy group with a carbon number of 1 to 4 and alkylamido group with a carbon number of 1 to 4; R is located at position 2, 3 or 4 of a benzene ring and selected from the group consisting of hydrogen, straight-chain and branched-chain alkyl and substituted alkyl groups with a carbon number of 1 to 4, alkylamino or alkyloxy group with a carbon number of 1 to 4 and alkylamido group with a carbon number of 1 to 4. In the formula II, R is selected from different substituted aryl groups. In the formula III, R is selected from hydrogen or cyano group. Experiments prove that the compound provided by the invention has good beta-secretase inhibitory activity and has wide application values as a beta-secretase inhibitor.

Synthesis, antibacterial, antifungal, and antioxidant evaluation of some new thiazole clubbed oxadiazole derivatives

A series of thiazole incorporated oxadiazole derivatives (6a-6f) was synthesized by reacting 2-chloro-N-(4-(4-substituted phenyl) thiazol-2-yl) acetamide with 5-pyridine-1,3,4-oxadiazole-2-thione using multistep solution phase chemistry. The synthesized compounds were structurally characterized on the basis of elemental analysis and using various spectral data. All the compounds were evaluated for their in vitro antibacterial, antifungal, and antioxidant activity. Some of the new compounds exhibited good antimicrobial and antioxidant activity and are suitable candidates for further scientific explorations.

2-Substituted-thio-N-(4-substituted-thiazol/1H-imidazol-2-yl)acetamides as BACE1 inhibitors: Synthesis, biological evaluation and?docking studies

In this work, a series of 2-substituted-thio-N-(4-substituted-thiazol/1H-imidazol-2-yl)acetamide derivatives were developed as β-secretase (BACE-1) inhibitors. Supported by docking study, a small library of derivatives were designed, synthesized and biologically evaluated in vitro. In addition, the selected compounds were tested with affinity (KD) towards BACE-1, blood brain barrier (BBB) permeability and cytotoxicity. The studies revealed that the most potent analog 41 (IC50 = 4.6 μM) with high predicted BBB permeability and low cellular cytotoxicity, could serve as a good lead structure for further optimization.

Synthesis and free radical scavenging activity of 2-alkyl/arylchalcogenyl-N-(4-aryl-1,3-thiazol-2-yl)acetamide compounds

The synthesis of a new series of organochalcogen-derivatives, 2-alkyl/arylchalcogenyl-N-(4-aryl-1,3-thiazol-2-yl)acetamides 5a-r, provided products in satisfactory yields, which varied from 42% to 95%. All these novel compounds were screened for their in vitro free radical scavenging activity against 2,2-diphenyl-2-picrylhydrazyl (DPPH) and 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radicals. Compounds 5 (m, h, i, f, q, g, l, c, n) were effective scavengers against the ABTS radical species but less effective on scavenging the DPPH radical, indicating that the antioxidant effect of these compounds were related to protonated radical scavenger activity.

Design, synthesis and biological screening of new 4-thiazolidinone derivatives with promising COX-2 selectivity, anti-inflammatory activity and gastric safety profile

Two series of new thiazolidin-4-one derivatives 4a-c and 8a-e were designed and prepared. All the synthesized compounds were evaluated for their in vitro COX-2 selectivity and anti-inflammatory activity in vivo. Compounds 8c and 8d showed the best overall

Design, synthesis and biological evaluation of thiazole- and indole-based derivatives for the treatment of type II diabetes

Present studies have shown that the lipid carrier has a significant role in several aspects of metabolic syndrome in A-FABP/ap2-deficient mice, including type 2 diabetes and atherosclerosis. 38 Thiazole- and indole-based derivatives were synthesized and investigated for their inhibitory effects on the production of LPS-stimulated TNF-α. Among them, 12b exhibited an excellent inhibitory efficiency compared to BMS309403 (95% vs. 85%) at the concentration of 10 μM and a binding affinity for ap2 with the apparent Ki values 33 nM. Oral administration of 12b at a dosage of 50 mg/kg effectively reduced the levels of plasma blood glucose, triglycerides, insulin, total cholesterol and alanine aminotransferase in high-fat/diet-induced obesity model. The results highlighted that 12b was a potent anti-diabetic agent.

Synthesis and fungicidal activity of 2-imino-3-(4-arylthiazol-2-yl)- thiazolidin-4-ones and their 5-arylidene derivatives

Five derivatives of 2-imino-3-(4-arylthiazol-2-yl)-thiazolidin-4-ones and a series of their 5-arylidene derivatives have been synthesized and tested for antifungal activity against seven agricultural fungi. 2-Imino-3-(2,4-dichloro-5- fluorophenylthiazol-2-yl)-4-thiazolidi-none and 2-imino-3-(2,4- dichlorophenylthiazol-2-yl)-4-thiazolidione, both of them new compounds, exhibited higher fungicidal effects than the other compounds prepared.
