Antibiotic resistance in bacteria exacerbates the issue of antimicrobial resistance. Bacteria that cause common or serious infections have evolved resistance to every new antibiotic that has been introduced into the market, to varying degrees, over several decades. Faced with this reality, one of society's most urgent needs is for new antimicrobial drugs with novel mechanisms of action. With this objective

N-glycoside formation. A number of the rhodanine derivatives, especially those with nitro or chloro groups in the aromatic ring, showed antibacterialactivity. N-beta-D-Glucopyranosyl-5-(4-nitrobenzylidene) rhodanine showed antiviralactivity by inhibition of viral RNA synthesis. Some effect on blood sugar levels also was observed with several rhodanines.
Methyl- and phenylmercury(II) complexes of 5-(4′-dimethylaminobenzylidene)rhodanine (HDABRd) and 5-(2′-thiophenomethylene)rhodanine (HTRd). The crystal and molecular structure of [HgPh(DABRd)] and [HgMe(TRd)]

)rhodanine (HDABRd) and 5-(2′-thiophenomethylene)rhodanine (HTRd) with methyl- and phenylmercury(II) acetate yielded [HgR(DABRd)] and [HgR(TRd)] (R=Me, Ph), respectively. These complexes were characterized and studied by IR and NMR (1H, 13C1H} and 199Hg) spectroscopy, and X-ray diffractometry, respectively. In both structures the rhodanine ligand coordinates to the mercury atom via its N(3) atom,
5-(4'-二甲基氨基亚苄基)罗丹宁(HDABRd)和5-(2'-噻吩亚甲基)罗丹宁(HTRd)与乙酸甲基和苯基汞(II)的反应生成[HgR(DABRd)]和[HgR(TRd) ](R = Me,Ph)。分别通过IR和NMR(1 H,13 C 1 H}和199 Hg)光谱和X射线衍射法对这些配合物进行了表征和研究。在两个结构中,若丹宁配体均通过其N(3)原子与汞原子配位,并且HgC(13)和HgN(3)几乎共线。汞原子还形成分子内和分子间的次级键。尤其是,Hg⋯S键使平行于b的锯齿形链中的[HgPh(DABRd)]分子缔合 Hg⋯O键连接着中心对称二聚体中的[HgMe(TRd)]分子。

A type of novel rhodanine-based 4-anilinoquinazoline, which designed the combination between quinazoline as the backbone and various substituted biological rhodanine groups as the side chain, have been synthesized, and their antiproliferative activities were also evaluated firstly. These compounds displayed good antiproliferative activity and EGFR-TK inhibitory activity. Among them, compound 8d showed good inhibitory activity (IC50 = 2.7 mu M for Hep G2, IC50 = 3.1 mu M for A549) and molecular docking of 8d into EGFR TK active site was also performed, this inhibitor well fitting the active site might well explain its excellent inhibitory activity.

An efficient and organo-catalyzed method has been developed for the synthesis of 5-arylidenethiazolidine-2,4-diones and 5-arylidene-2-thioxothiazolidin-4-ones via Knoevenagel condensation of arylaldehydes 1 and 2,4-thiazolidinedione 2a/2-thioxothiazolidin-4-one 2b under mild conditions. Urea-adduct 4 and azomethine 5 also afford arylidene-products 3 by reacting with 2a-b via addition-elimination reaction. This protocol has the features of use of inexpensive, ecofriendly readily available, effective catalyst system viz. urea/thiourea, avoidance of volatile solvents, excellent yield and simple work-up procedure.
