Abstract The YAP-TEAD protein-protein interaction (PPI) is a critical event known to mediate YAP oncogenic functions downstream of the Hippo pathway. Current advanced pharmacological agents which aim at inhibiting function do so by engaging into lipid pocket TEAD. Thereby consequences direct disruption interface and TEADs remain unexplored. Here we report identification IAG933, first molecule able potently directly disrupt YAP/TAZ-TEADs PPI with suitable properties enter in clinical trial....
5011 Background: Patients with mCRPC inevitably develop resistance to available therapies, eg, novel hormonal agents (NHAs), and experience disease progression.

Acylfulvenes comprise a family of semisynthetic natural product derivatives with potent antitumor activities. Previous studies indicated that acylfulvenes are bioactivated by NADPH-dependent alkenal/one reductase (AOR), presumably generating intermediates the capacity to alkylate cellular targets, such as DNA, proteins, and glutathione. This process is thought induce apoptosis, chemical biochemical pathways involved topics current investigation. In this study, four acylfulvene analogues were...
