This invention is in the field of medicinal chemistry. In particular, the invention relates to a new class of small-molecules having sulfonamido-1-hydroxynaphthalene structure which function as inhibitors of Mcl-1 protein, and their use as therapeutics for the treatment of cancer and other diseases.
We report in this work the discovery of novel allosteric MEK inhibitors by pharmacophore modeling and virtual screening. Two out of 13 virtual hit compounds were identified as MEK kinase inhibitors using a MEK1 binding assay. Structural derivations on the hit compound M100 (IC50 = 27.2 +/- 4.5 mu M in RAF-MEK cascading assay) by substituent transformation and bioisosterism replacement have led to the synthesis of a small library of carbazoles. The enzymatic studies revealed the preliminary structure-activity relationships and the derivative 22k (IC50=12.8 +/- 0.5 mu M) showed the most potent inhibitory effect against Raf-MEK cascading. Compound 7 was discovered as toxic as M100 to tumor cells whereas safer to HEK293 cells (IC50 > 100 mu M) than M100 (IC50 = 8.9 +/- 2.0 mu M). It suggests that carbazole is a good scaffold for the design of novel MEK inhibitors for therapeutic uses. More importantly, the developed pharmacophore model can serve as a reliable criterion in novel MEK inhibitor discovery. (C) 2019 Elsevier Masson SAS. All rights reserved.

A novel series of non-peptide proteasome inhibitors (PIs) that act on chymotrypsin-like (ChT-L) of the proteasome were developed. These PIs bearing 4-aromatic sulfonyl naphthalene-based scaffold and Leu-boronic moiety as covalent bonding group displayed far better activity than PI-8182 for inhibiting ChT-L in preliminary biological activity test. The results showed that 2a (IC50 = 6.942 μM, MCF-7)
