Synergism of fused bicyclic 2-aminothiazolyl compounds with polymyxin B against: Klebsiella pneumoniae

A series of fused bicyclic 2-aminothiazolyl compounds were synthesized and evaluated for their synergistic effects with polymyxin B (PB) against Klebsiella pneumoniae (SIPI-KPN-1712). Some of the synthesized compounds exhibited synergistic activity. When 4 μg ml-1 compound B1 was combined with PB, it showed potent antibacterial activity, achieving 64-fold reduction of the MIC of PB. Furthermore, compound B1 showed prominent synergistic efficacy in both concentration gradient and time-kill curves in vitro. In addition, B1 combined with PB also exhibited synergistic and partial synergistic effect against E. coli (ATCC25922 and its clinical isolates), Acinetobacter baumannii (ATCC19606 and its clinical isolates), and Pseudomonas aeruginosa (Pae-1399).

Synthesis, single crystal X-ray, Hirshfeld surface analysis and characterization of novel 4-(2,4-dichlorophenyl)-N-(2,6-dichlorophenyl)-1,3-thiazol-2-amine

In the present study, the spectroscopic characterization of a novel thiazole scaffold was studied. The formation of title compound 4-(2,4-dichlorophenyl)-N-(2,6-dichlorophenyl)-1,3-thiazol-2-amine(6) was evidenced through the changes in FTIR, 1H NMR, LCMS Data. The X-ray diffraction studies revealed that compound (6) crystallized in monoclinic crystal system with P21/c Space group with Z = 4. The percentage of intermolecular contacts contributing to the Hirshfeld surface in thiazole crystal was resolved by Hirshfeld surface analyses with 2D fingerprint plots.

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.

Improved Procedures for the Preparation of Cycloalkyl-, Arylalkyl-, and Arylthioureas

An improved procedure for the preparation of arylthioureas consists of the reaction of benzoyl isothiocyanate with anilines in acetone and debenzoylation of the resultant N-aryl-N'-benzoylthioureas with 5percent aqueous sodium hydroxide.Bicycloalkylthioureas and N-(arylalkyl)thioureas (e.g. 9H-9-fluorenylthiourea) are directly prepared from the corresponding isothiocyanates and ammonia.

Synthesis & Pharmacological Evaluation of Ethyl 3-Substituted-phenyl-2-methylmercapto/ phenyl/ methyl-4(3H)-pyrimidone-5-carboxylates

A number of ethyl 3-substituted-phenyl-2-methylmercapto/ phenyl/ methyl-4(3H)-pyrimidone-5-carboxylates (V) have been prepared by the reaction of amidines (III) with diethyl ethoxymethylenemalonate.In order to confirm the structure (V), ethyl 3-(2'-methylphenyl)-2-methylmercapto-4(3H)pyrimidone-5-carboxylate (103) has been transformed into the earlier synthesised 3-(2'-methylphenyl)-2-methylmercapto-4(3H)-pyrimidone (115) by decarboxylation of 3-(2'-methylphenyl)-2-methylmercapto-4(3H)-pyrimidone-5-carboxylic acid (114), obtained by the alkaline hydrolysis of 103.Someof these compounds have shown antiinflammatory, diuretic and antipassive cutaneous anaphylaxis activities.
