Discovery of N-(3,4-Dimethylphenyl)-4-(4-isobutyrylphenyl)-2,3,3a,4,5,9b-hexahydrofuro[3,2-c]quinoline-8-sulfonamide as a Potent Dual MDM2/XIAP Inhibitor was written by Wu, Zhongzhi;Gu, Lubing;Zhang, Sicheng;Liu, Tao;Lukka, Pradeep B.;Meibohm, Bernd;Bollinger, John C.;Zhou, Muxiang;Li, Wei. And the article was included in Journal of Medicinal Chemistry in 2021.Formula: C6H5Br2N This article mentions the following:
Murine double minute 2 (MDM2) and X-linked inhibitor of apoptosis protein (XIAP) are important cell survival proteins in tumor cells. As a dual MDM2/XIAP inhibitor reported previously, compound MX69 has low potency with an IC50 value of 7.5μM against an acute lymphoblastic leukemia cell line EU-1. Herein, we report the structural optimization based on the MX69 scaffold, leading to the discovery of a 25-fold more potent analog 14 (IC50 = 0.3μM against EU-1). We demonstrate that 14 maintains its mode of action by dual targeting of MDM2 and XIAP through inducing MDM2 protein degradation and inhibiting XIAP mRNA translation, resp., which resulted in cancer cell growth inhibition and cell death. The results strongly suggest that the scaffold based on 14 is promising for further optimization to develop a new therapeutic agent for leukemia and possibly other cancers where MDM2 and XIAP are dysregulated. In the experiment, the researchers used many compounds, for example, 3,4-Dibromoaniline (cas: 615-55-4Formula: C6H5Br2N).
3,4-Dibromoaniline (cas: 615-55-4) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbonbromine bond is electrophilic in nature. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.Formula: C6H5Br2N
