Phenylamino-pyrimidine (PAP) — derivatives: a new class of potent and highly selective PDGF-receptor autophosphorylation inhibitors
摘要:
Phenylamino-pyrimidines represent a novel class of inhibitors of the PDGF-receptor autophosphorylation with a high degree of selectivity versus other tyrosine and serine/threonine kinases. Optimum activity of ca 10 nM (IC50) was observed when the phenylamino-group which is attached to the pyrimidine carries a benzamide-moiety with a lipophilic substituent in 4-position.

A series of novel 2-phenylaminopyrimidine (PAP) derivatives structurally related to STI-571 were designed and synthesized. The abilities of these compounds to inhibit proliferation were tested in human chronic myeloid leukemia K562 cells. (E)-3-(2-bromophenyl)-N-[4-methyl-3-(4-pyridin-3-yl-pyrimidin-2-ylamino)phenyl]acrylamide(12d) was the most effective cell growth inhibitor and was 3-fold more potent than STI-571.
A series of new anilino substituted pyrimidine linked pyrrolo[2,1-c][1,4]benzodiazepine (PBD) conjugates were prepared and evaluated for their anticancer activity. The effects of four promising PBD conjugates on cell cycle of cancerous cell line A375 were investigated. These compounds showed the characteristic features of apoptosis like enhancement in the levels of p53, release of cytochrome c, and
制备了一系列新的苯胺基取代的嘧啶连接的吡咯并[2,1- c ] [1,4]苯并二氮杂(PBD)缀合物,并评估了其抗癌活性。研究了四种有前景的PBD缀合物对癌细胞系A375的细胞周期的影响。这些化合物显示出凋亡的特征,例如p53水平的增强,细胞色素c的释放以及PARP的裂解。
Synthesis and apoptosis inducing ability of new anilino substituted pyrimidine sulfonamides as potential anticancer agents
A series of anilino substituted pyrimidine sulfonamides were prepared and evaluated for their anticancer activity. These sulfonamides showed promising activity with IC50 values ranging from 5.6 to 12.3 μM. The detailed biological aspects of some of the promising compounds (3d, 3e and 3g) on the K562 cell line were studied. Interestingly, compounds induced G1 cell cycle arrest and down regulation of
制备了一系列苯胺基取代的嘧啶磺酰胺,并对其抗癌活性进行了评估。这些磺酰胺类化合物显示出令人鼓舞的活性,IC 50值为5.6至12.3μM。研究了一些有前途的化合物(3d,3e和3g)在K562细胞系中的生物学细节。有趣的是,化合物诱导了G1细胞周期的阻滞和G1期细胞周期调节蛋白(如细胞周期蛋白D1,CDK4)的下调。这些化合物还显示出对NF-κB及其下游靶基因Akt1的抑制和AKt ser 474蛋白的磷酸化形式。代表性化合物3e之一 可以被认为是其发展为新型抗癌药的潜在先导。
