Within the framework of our attempts to synthesize pleiotropic anti-inflammatory agents, we have synthesized some chalcones and their corresponding 3,4-pyrrolyl derivatives. Chalcones constitute a class of compounds with high biological impact. They are known for a number of biological activities, including anti-inflammatory and free radical scavenging activities. They inhibit several enzymes implicated in the inflammatory process, such as lipoxygenase, cyclooxygenase (COX) and lysozymes. The synthesized pyrroles have been studied for: (1) their in vitro inhibition of lipoxygenase; (2) their in vitro inhibition of COX; (3) their in vitro inhibition of lipid peroxidation; (4) their interaction with the stable, N-centered, free radical, 2,2-diphenyl-1-picrylhydrazyl (DPPH); (5) their inhibition on interleukin-6 (IL-6); (6) their anti-proteolytic activity; and (7) their in vivo anti-inflammatory activity using carrageenan-induced rat paw edema. Their physicochemical properties were determined to explain the biological results. Lipophilicity was experimentally determined. 2i and 2v were found to be promising multifunctional molecules with high antiproteolytic and anti-inflammatory activities in combination with anti-interleukin-6 activity.
在我们合成多效抗炎剂的框架内,我们合成了一些查尔酮及其相应的3,4-吡咯衍生物。查尔酮是一类具有高生物影响的化合物。它们因多种生物活性而知名,包括抗炎和清除自由基的活性。它们能够抑制几种与炎症过程相关的酶,如脂氧化酶、环氧合酶(COX)和溶菌酶。合成的吡咯类化合物已被研究以下方面:(1) 其对脂氧化酶的体外抑制;(2) 其对COX的体外抑制;(3) 其对脂质过氧化的体外抑制;(4) 其与稳定的N中心自由基2,2-二苯基-1-苦味肼(DPPH)的相互作用;(5) 对白细胞介素-6 (IL-6) 的抑制;(6) 其抗蛋白酶活性;(7) 通过卡拉胶诱导的大鼠足部水肿进行的体内抗炎活性。为了解释生物结果,测定了它们的物理化学性质。脂溶性是通过实验确定的。2i和2v被发现是有前景的多功能分子,具有很高的抗蛋白酶和抗炎活性,同时还具备抗白细胞介素-6的活性。
