Solution-phase microwave assisted parallel synthesis of N,N′-disubstituted thioureas derived from benzoic acid: Biological evaluation and molecular docking studies
摘要:
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. H-1 & C-13 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 IC50 of 1.67 mu M. The docking scores correlate with the IC50 values of inhibitors. (C) 2013 Elsevier Masson SAS. All rights reserved.

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 5% aqueous sodium hydroxide. Bicycloalkylthioureas and N-(arylalkyl)thioureas (e.g., 9H-9-fluorenylthiourea) are directly prepared from the corresponding isothiocyanates and ammonia.
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).
An efficient methodology for the synthesis of 4-amino-2-iminothiazole derivatives has been developed. The synthesis involves the cyclization of unsymmetrical 1-aroyl-3-arylthioureas with a variety ...
