Benzoylthioureas: Design, synthesis and antimycobacterial evaluation

Background: New drugs and strategies to treat tuberculosis (TB) are urgently needed. In this context, thiourea derivatives have a wide range of biological activities, including anti-TB. This fact can be illustrated with the structure of isoxyl, an old anti-TB drug, which has a thiourea as a pharmacophore group. Objective: The aim of this study is to describe the synthesis and the antimycobacterial activity of fifty-nine benzoylthioureas derivatives. Methods: Benzoylthiourea derivatives have been synthesized and evaluated for their activity against Mycobacterium tuberculosis using the MABA assay. After that, a structure-activity relationship study of this series of compounds has been performed. Results and Discussion: Nineteen compounds exhibited antimycobacterial activity between 423.1 and 9.6 μM. In general, we observed that the presence of bromine, chlorine and t-Bu group at the para-position in benzene ring plays an important role in the antitubercular activity of Series A. These substituents were fixed at this position in benzene ring and other groups such as Cl, Br, NO2 and OMe were introduced in the benzoyl ring, leading to the derivatives of Series B. In general, Series B was less cytotoxic than Series A, which indicates that the presence of a substituent at benzoyl ring contributes to an improvement in both antimycobacterial activity and toxicity profiles. Conclusion: Compound 4c could be considered a good prototype to be submitted to further structural modifications in the search for new anti-TB drugs, since it is 1.8 times more active than the first line anti-TB drug ethambutol and 0.65 times less active than isoxyl.

Hirshfeld surface analysis of some new heteroleptic Copper(I) complexes

Seven new coordination complexes namely, [Cu(T1) (I) (PPh3)2] (CT1), [Cu(T2) (I) (PPh3)2] (CT2), [Cu(T3) (I) (PPh3)2] (CT3), [Cu(T4) (I) (PPh3)2] (CT4), [Cu(T5) (I) (P

Antitubercular activities of the novel synthesized 1,2,4-triazole derivatives

1,2,4-Triazoles exert antimycobacterial activity by inhibiting the cell wall biosynthesis. In an attempt to developing lead compounds exhibiting antitubercular activities, a series of 1,2,4-triazole derivatives were synthesized by introducing various substitutes into a scaffold and the antitubercular activity was evaluated. The most potent compounds 3e and 8d showed their minimum inhibitory concentrations against Mycobacterium tuberculosis as 12.5 ??M. The results indicate that those compounds can be considered as leads for further development of new 1,2,4-triazole type candidates with high antitubercular activities.

Design, syntheses and evaluation of benzoylthioureas as urease inhibitors of agricultural interest

Urea is one of the most used nitrogen fertilizers worldwide. However, occurrence of urea hydrolysis to ammonia and carbon dioxide on soil surface, catalyzed by soil ureases, considerably reduces nitrogen availability to crops. In this study, we describe the design, synthesis and screening of sixty five benzoylthioureas (BTUs) for their ability to inhibit purified jack bean and soil ureases. BTUs were readily obtained in one pot, two steps synthesis with no need of cumbersome procedures for product purification. In vitro assays revealed BTUs 11, 12, 14, 19-22 and 37 as the most active jack bean urease inhibitors. Such BTUs were found to be able to bind to both catalytic and allosteric sites of urease, acting therefore as mixed-type inhibitors. Out of 28 compounds that effectively inhibited soil ureases activity, BTUs 3, 6, 10, 12, 16, 19 and 22 were determined to be more potent than the reference inhibitor N-(butyl) thiophosphoric triamide (NBPT; 40%). The other 22 BTUs were as potent as NBPT on soil ureases. The temperature-tolerance of BTUs, along with their ability to inhibit soil ureases, makes of this class of compounds potential additive for urea-based fertilizers.

Solution-phase microwave assisted parallel synthesis of N,N′-disubstituted thioureas derived from benzoic acid: Biological evaluation and molecular docking studies

An efficient and facile microwave-assisted solution phase parallel synthesis for a 26-member library of N,N′-disubstituted thiourea analogs were accomplished successfully. The reaction time for synthesis of analogs was drastically reduced from a reported 8-12 h to only 10 min. Compounds were more than 95% pure, as characterized by modern analytical techniques, i.e. 1H & 13C NMR and FT-IR. The solid phase structural analysis has also been performed by single crystal XRD analysis. Synthesized compounds were preliminary screened for their in vitro urease inhibition and antifungal activity. Most of the compounds were found to be potent inhibitors of urease. However, the most significant activity was found for 11 with IC 50 of 1.67 μM. The docking scores correlate with the IC 50 values of inhibitors.

[4-(Imidazol-1-yl)thiazol-2-yl]phenylamines. A novel class of highly potent colchicine site binding tubulin inhibitors: Synthesis and cytotoxic activity on selected human cancer cell lines

Synthesis and cytotoxic activity in the submicromolar range of a series of [4-(imidazol-1-yl)thiazol-2-yl]-phenylamines are described. Cell cycle dependent cytotoxicity on RKO human colon carcinoma cells with inducible expression of p27kip1 and the influence on microtubule formation were investigated. Considering the significant correlation between the IC50 values of tubulin polymerization inhibition, [3H]colchicine competition, and cytotoxicity of the investigated compounds, tubulin is the main cellular target. The inhibition of microtubule formation was shown to be mediated by interference with the colchicine binding site of tubulin. In depth analysis of the investigated compounds allowed the identification of modifications that altered the pharmacological profile of the compounds from a mitosis-inducing phenotype to a G1 cell cycle arresting phenotype.

Substituted N-phenylisothioureas: Potent inhibitors of human nitric oxide synthase with neuronal isoform selectivity

S-Ethyl N-phenylisothiourea (4) has been found to be a potent inhibitor of both the human constitutive and inducible isoforms of nitric oxide synthase. A series of substituted N-phenylisothiourea analogues was synthesized to investigate the structure-activity relationship of this class of inhibitor. Each analogue was evaluated for human isoform selectivity. One analogue, S-ethyl N-[4-(trifluoromethyl)phenyl]isothiourea (39), exhibited 115-fold and 29-fold selectivity for the neuronal isoform versus the inducible and endothelial derived constitutive isoforms, respectively. Studies have shown the substituted N-phenylisothiourea 39 binds competitively with L,-arginine.
