Design, Synthesis, in vitro Antiproliferative Activity Evaluation of 2-Acylaminothiopene-3-carboxamide Derivatives
摘要:
A series of 2-alkanoylamidothiophene-3-carboxamide derivatives were synthesized based on the hit compound 1. The anti-proliferative activity of all the compounds in vitro against MGC-803 (stomach) and HCT-116 (colon) cancer cell lines using SRB assays were tested. Several compounds showed improved anti-proliferative activity against MGC-803 and HCT-116. SAR study revealed that chlorine substituent in the 2-acetylamino part was important for anti-proliferative activity. 5a, 11b, 11c and lid were the most potent compounds against MGC-803 (IC(50)s = 2.32-2.95 mu M), and 5a and 11c also showed good anti-proliferative activity against HCT-116 cells (IC(50)s = 3.41-3.75 mu M). In addition, the anti-proliferative activity of llb and lid could be attributed to the apoptosis in HCT116 cells via caspase 3 activation, confirmed by flow cytometry assay and western blot analysis. Meanwhile, lib and lid decreased the mitochondrial membrane potential (MMP) in HCT116 cells.

on the binding geometry. We present an example in which minor chemical modifications within one inhibitor series lead to surprisingly different bindingmodes. X‐ray structure determination of eight inhibitors derived from one core scaffold resulted in four different bindingmodes in the asparticprotease endothiapepsin, a well‐established surrogate for e.g. renin and β‐secretase. In addition, we suggest

A method of combating phytopathogenic diseases on plants and harvested food crops which comprises applying to a plant, to the seed of a plant, to the locus of the plant or seed or to a harvested food crop a fungicidally effective amount of a compound of the general formula (1), and fungicidals compositions containing these compounds.
