  Discovery of pyridine tetrahydroisoquinoline thiohydantoin derivatives with low blood-brain barrier penetration as the androgen receptor antagonists

  摘要：

  Prostate cancer (PC) is the most diagnosed type of malignancy in men and the major frequently cause of cancer-related death worldwide. The androgen receptor (AR) has become a promising drug target for the treatment of PC. Here, we reported the design, optimization and evaluation of pyridine tetrahydroisoquinoline thiohydantoin derivatives with improved activity and safety as potent AR antagonists. The most promising compound 42f exhibited potent inhibitory activity on AR and strongly blocked AR nuclear translocation. Moreover, 42f displayed promising in vitro antitumor activity toward AR-dependent prostate cancer cell lines (LNCaP) and also demonstrated therapeutic effects in LNCaP xenograft tumor model in mice (TGI: 79%) with no apparent toxicity observed in vivo. More importantly, 42f showed negligible penetration of the brain-blood barrier (BBB) compared with enzalutamide. These results provide a foundation for the development of a new class of androgen receptor antagonists for potential therapeutics against PC with lower seizurogenic risk for patients.

  Synthesis of a New Diaminodithiol Bifunctional Chelator for Radiolabeling Biomolecules with Indium(III)

  摘要：

  The synthesis of a new bifunctional ligand 1-(p-carboxybenzyl)-N,N'-bis-[1,1-dimethyl-1-(p-methoxybenzylthio)ethyl]-ethylenediamine-N,N'-diacetic acid, di-t-butyl ester (1, nbi6ss) is described. It consists of a carboxybenzyl group substituted on a carbon atom of the ethylenediamine moiety of a hexadentate ligand, which has been found to have a very high affinity for In(III). The gem-dimethylthiol groups and the carboxylic acid groups of the ligand were protected by groups that can be removed under mild conditions after conjugation to a peptide or protein.
