potential target for the discovery of chemosensitizers and anticancer drugs. Amentoflavone (AMF) is reported to be a selective PARP-1 inhibitor. Here, structural modifications and trimming of AMF have led to a series of AMF derivatives (9a–h) and apigenin–piperazine/piperidine hybrids (14a–p, 15a–p, 17a–h, and 19a–f), respectively. Among these compounds, 15l exhibited a potent PARP-1 inhibitory effect
The discovery of a novel series of β-methyltryptophan (β MeTrp) derivatives as selective and orallyactive non-peptide somatostatin receptor 2 (SSTR2) agonists for the treatment of Type 2 diabetes is described. In our previous research, Compound A, β-MeTrp derivative with highly potent and selective SSTR2 agonistic activity IC50 (SSTR2/SSTR5) = 0.3/>100 (nM), was identified as a drug candidate for
