YAP-IN-1

YAP-IN-1 (Compound (+) -1) is an autophagy inhibitor specifically targeting YAP1. It binds to the Hippo pathway transcription factor YAP1 with a Kd of 9.13 μM, promoting its degradation through the chaperone-mediated autophagy (CMA) pathway. This process inhibits the Rab7-mediated fusion of autophagosomes with lysosomes and decreases autophagy levels without affecting lysosomal function. YAP-IN-1 shows potential for cancer research, including in hepatocellular carcinoma and breast cancer.
