ADS-J1 is an HIV-1 entry inhibitor that potently inhibits seminal amyloid fibrillization and block fibril-mediated enhancement of viral infection. Semen-derived amyloid fibrils, comprising SEVI (semen-derived enhancer of viral infection) fibrils and SEM1 fibrils, may remarkably enhance HIV-1 sexual transmission and are potential targets for the development of an effective microbicide.
DJ101is an effective and metabolically stable inhibitor of tubulin. It can circumvent the drug efflux pumps responsible for multidrug resistance of existing tubulin inhibitors.
DPC-AJ1951 is a peptide agonist of the parathyroid hormone (PTH)/PTH-related peptide receptor (PPR; EC50 = 0.15 nM in HEK293 cells expressing human PPR). It induces cAMP production in SAOS-2 and UMR106 cells that endogenously express human and rat PPR, respectively (EC50s = 2.2 and 1.1 nM, respectively). DPC-AJ1915 stimulates osteoclast-mediated bone resorption in fetal rat long-bone explant cultures and increases collagen synthesis and cell proliferation in neonatal mouse parietal bone explants. In vivo, DPC-AJ1951 normalizes serum calcium levels in thyroidparathyroidectomized rats.
