18 µM). The anticancer activity of potent derivatives (3b and 3d) against A549 cancer cell line was further confirmed by flow cytometry based approach. DNAbinding interactions of the pyrazoline derivatives 3b and 3d have been carried out with calf thymus DNA (Ct-DNA) using absorption, fluorescence and viscosity measurements, circular dichroism and cyclic voltammetry. Antioxidant potential of N-formyl
Abstract Thirty semicarbazone and thiosemicarbazone derivatives (2a–w and 4a–g) from chalcones containing furan and thiophene ring were designed and synthesized. They were characterized by IR, 1H NMR, 13C NMR and HRMS. The crystal structure of compound 2r was characterized by single crystal X-ray diffraction. It crystallizes in the monoclinic system with space group P21/c. The insecticidal activity
摘要 设计并合成了来自含有呋喃和噻吩环的查耳酮的30 种缩氨基脲和缩氨基硫脲衍生物(2a - w和4a - g)。它们通过 IR、1 H NMR、13 C NMR 和 HRMS进行表征。化合物2r的晶体结构通过单晶X射线衍射表征。它在空间群为P 2 1 / c的单斜晶系中结晶。合成的化合物对白斑病和菜青虫的杀虫活性进行了筛选使用β-氯氰菊酯作为比较标准。结果表明,它们中的大多数具有显着的杀虫活性。其中,化合物2e-g对L表现出比 β-氯氰菊酯更好的活性。分离和P。油菜。化合物2p还具有比 β-氯氰菊酯更好的抗P活性。油菜。这些化合物的杀虫活性是首次报道。
A series of novel beta-mercapto carbonyl compounds (3a-z), methyl 2-(3-oxo-1,3-diarylpropylthio)acetate, were synthesized and characterized via iodine-catalyzed addition of methyl thioglycolate to chalcones (1a-z).
