新型DFG-out RAF /血管内皮生长因子受体2(VEGFR2)抑制剂的设计和合成:3. 5-氨基连接的噻唑并[5,4- d ]嘧啶和噻唑并[5,4- b ]吡啶衍生物的评价
摘要:
我们的目的是发现具有强活性和足够口服吸收的RAF /血管内皮生长因子受体2(VEGFR2)抑制剂,因此,我们选择了5-氨基连接的噻唑并[5,4- d ]嘧啶衍生物作为前导物化合物具有潜在的激酶抑制活性和所需的溶解性。根据BRAF的X射线共晶体结构数据,设计了新颖的1-氰基-1-甲基乙氧基叔取代基,以占据BRAF“后袋”的疏水区域。另外,我们发现胺连接基的N-甲基化可以控制扭曲的分子构象,从而导致溶解度的提高。这些方法产生了N-甲基噻唑并[5,4 - b ]吡啶-5-胺衍生物5。为了使体内功效最大化,我们尝试了5的成盐作用。我们的结果表明,苯磺酸盐一水合物盐形式(5c)在溶解度和口服吸收方面均表现出显着改善。由于改善的理化特性,化合物5c在HT-29异种移植模型中显示出了抗肿瘤退行的功效。

Mn(I) complexes are capable of H–P bond activation. This activation mode enables a general method for the hydrophosphination of internal and terminal α,β-unsaturatednitriles. Metal−ligand cooperation, a strategy previously not considered for catalytic H–P bond activation, is at the base of the mechanistic action of the Mn(I)-based catalyst. Our computational studies support a stepwise mechanism for the

Clever positioning: A bipyridine ligand incorporating a remote anionic sulfonate group directs iridium-catalyzed borylation to the meta-position on a range of amide-containing arenes. It is proposed that this selectivity is a result of a hydrogen bonding interaction to correctly position the iridium metal centre in the crucial C−H activation.
