A library of sixty-five chalcones was prepared for screening against the protein phosphatase, cdc25B. From this library, thirteen compounds were found having good inhibitory activity. Two compounds have excellent activity and can be used for the design of more potent antiproliferative agents.
A large series of chalcones were synthesized and studied for activity against Candida albicans. The SAR analysis showed that the antifungal activity was highly dependent on the substitution pattern of the aryl rings and correlated to a large extent with the ability of compounds to interact with sulfhydryl groups. The most active were the hydroxylated chalcones as their activity related to the location

A series of new 3-phenyl-5-aryl-N-(4-sulfamoylphenyl)-4,5-dihydro-1H-pyrazole-1-carboxamide derivatives was designed here, synthesized, and studied for carbonic anhydrase (CAs, EC 4.2.1.1) inhibitory activity against the human (h) isozymes I, II, and VII (cytosolic, off-target isoforms), and IX and XII (anticancer drug targets). Generally, CA I was not effectively inhibited, whereas effective inhibitors
在此设计,合成并研究了一系列新的3-苯基-5-芳基-N-(4-氨磺酰基苯基)-4,5-二氢-1H-吡唑-1-羧酰胺衍生物(CAs,EC 4.2 .1.1)对人(h)同工酶I,II和VII(胞质,脱靶同工型)和IX和XII(抗癌药物靶标)的抑制活性。通常,CA I没有被有效抑制,而针对CA II(KI的范围为5.2-233 nM)和VII(KI的范围为2.3-350 nM)都鉴定出了有效的抑制剂。但是,CA IX和XII是这类抑制剂最易受感染的同工型。特别地,在吡唑啉3位带有未取代的苯环的化合物对CA IX显示出1.3-1.5 nM KIs。相反,在芳族骨架的相同位置具有4-卤代苯基的衍生物的一个子集甚至达到了针对CA XII的亚纳摩尔KIs(0.62-0.99 nM)。与CA IX和XII的对接研究用于阐明驱动肿瘤相关CA优先抑制的衍生物结合模式。鉴定出的有效和选择性的CA IX / XI

chromatography (HPLC). Human (h) carbonic anhydrase (CA, EC 4.2.1.1) isoforms hCA I and II and Mycobacterium tuberculosis β-CA encoded by the gene Rv3273 (mtCA 3) inhibition activity was investigated with the synthesised compounds which showed promising inhibition. The KIs were in the range of 54.6 nM-1.8 µM against hCA I, in the range of 32.1 nM-5.5 µM against hCA II and of 127 nM-2.12 µM against mtCA

A new series of 1-(4-aminosulfonylphenyl)-3,5-diaryl pyrazolines (5) was synthesized by the reaction of appropriate chalcones 3 with 4-hydrazinobenzenesulfonamide hydrochloride (4) in ethanol in the presence of catalytic amount of acetic acid. All newly synthesized compounds were in vivo evaluated for their antiinflammatory activity using carrageenan-induced rat paw edema assay. Five of the newly synthesized
