ABT1 Inhibitors

ABT1 inhibitors encompass a variety of chemical compounds that chiefly attenuate the functional activity of ABT1 through the intricate regulation of signaling cascades that converge upon ABT1. The inhibition of PI3K by Wortmannin and LY294002, for instance, precludes the phosphorylation of AKT, a pivotal kinase in the PI3K/AKT/mTOR axis, thereby indirectly thwarting the activation of ABT1. Similarly, Everolimus and Rapamycin exert their inhibitory effect by binding to FKBP12 and subsequently hampering mTOR, a kinase that is quintessential for ABT1's activation via phosphorylation. The suppression of AKT phosphorylation is also the mechanism of action for Triciribine, which specifically targets AKT, further impeding ABT1 activation. Dasatinib and PP2 disrupt ABT1 function by inhibiting Src family kinases, which play a role in various signaling pathways, including those that regulate ABT1. Moreover, ABT1 activity is indirectly modulated by inhibitors that target the MAPK signaling pathways. PD98059 and U0126, as specific inhibitors of MEK1/2, along with SB203580, which targets p38 MAPK, and SP600125, an antagonist of JNK, collectively contribute to the fine-tuning of ABT1's role in cell signaling. These inhibitors collectively diminish the cross-talk between the MAPK pathway and the pathways that ABT1 is a part of, leading to a decrease in ABT1's functional engagement. BKM120, with its broad spectrum inhibition of PI3K isoforms, amplifies the blockade of ABT1 activation.
