A simple, efficient and environmentally benign protocol has been developed for the one-pot, multicomponent synthesis of medicinallyimportant tetrahydrobenzo[b]pyrans and pyran-annulated heterocycles using a commercially available, inexpensive, non-toxic, and biodegradable tris-hydroxymethylaminomethane (THAM) as a novel organocatalyst. Ambient reaction conditions, wide scope, avoidance of conventional

2-c]quinoline based structural analogues was synthesized using one-pot multicomponent condensation between 2,4-dihydroxy-1-methylquinoline, malononitrile, and diverse un(substituted) aromatic aldehydes. The synthesized compounds were evaluated for their anti-inflammatory and cytotoxicity activity. Initially, all the compounds were evaluated for the percent inhibition of cytokinerelease, and cytotoxicity activity
使用2,4-二羟基-1-甲基喹啉,丙二腈和各种未取代的芳香醛之间的一锅多组分缩合反应,合成了一系列基于吡喃并[3,2- c ]喹啉的结构类似物。评价合成的化合物的抗炎和细胞毒性活性。最初,评估所有化合物对细胞因子释放的抑制百分比,并确定细胞毒性活性和50%抑制浓度(IC 50)。根据主要结果,在人外周血单核细胞(hPBMC)分析中进一步研究了它们抑制TNF-α产生的能力。筛选结果表明,化合物4c,4f,4i,和4j被发现是该系列抗炎和抗癌活性最活跃的候选药物。讨论了结构与活性之间的关系,并指出吡喃并[3,2- c ]喹诺酮结构基序的C4位芳基环上的3-取代似乎是TNF-α和IL-6抑制作用的重要位置。以及抗癌活性。然而,具有吸电子,给电子,空间受阻和杂芳基取代的结构多样性真诚地影响了炎症和抗癌活性。
