噻吩并[2,3 - b ]喹啉-2-羧酰胺和环烷基[ b ]噻吩并[3,2 - e ]吡啶-2-羧酰胺衍生物的合成及细胞毒性
摘要:
噻吩并[2,3-的七十九衍生物b〕喹啉,四氢[2,3- b ]喹啉,二氢环戊二烯并[ b ]噻吩并[3,2- ë ]吡啶,环庚并[ b ]噻吩并[3,2- ë ]吡啶和六氢环辛基[ b ]噻吩并[3,2- e ]吡啶是合成的或可商购的,并测试了它们对HCT116,MDA-MB-468和MDA-MB-231人癌细胞系的抗增殖活性。最有效的八种化合物对所有细胞系均具有活性,IC 50值在80–250 nM范围内。一般而言,六氢环辛基[ b ]噻吩并[3,2- e当较大的环烷基环与吡啶环稠合时,]吡啶最活跃,活性增加。

There is provided an aminophenoxyacetic acid derivative of the following formula (I):
wherein, R1, R2, R3 and R4 are, independent from each other, alkoxy group, alkyl group or aryl group, etc.; E1 and E2 are oxygen atom, sulfur atom, etc.; n is 0 to 5; X and Y are alkylene group, cycloalkylen group, or alkenylen group; Q is phenyl group which may be substituted or benzoyl group, etc,
or a pharmaceutically acceptable salt thereof.
These compounds have neuroprotective effects by inducing calbindin D28Kd, one of Ca2+-binding proteins.
Abstract A series of eighteen pyrazole-imidazole-triazole hybrid (2-(4-((2-(substituted-1H-pyrazol-1-yl)-4-phenyl-1H-imidazol-1-yl)methyl)-1H-1,2,3-triazol-1-yl)-N-(substituted)phenylacetami- de) (6a-6r) are synthesized through click reaction between in situ generated 2-azido-N-substituted acetamide and N-propargylated pyrazole-imidazole derivatives which in turn has been obtained regioselectively
