Multiple myeloma (MM) is the second most common haematological malignancy. Almost all patients with MM eventually relapse, and most recommended treatment protocols for the patients with relapsed refractory MM comprise a combination of drugs with different mechanisms of action. Therefore novel drugs are in urgent need in clinic. Bcl-2 inhibitors and HDAC inhibitors were proved their anti-MM effect in clinic or under clinical trials, and they were further discovered to have synergistic interactions. In this study, a series of Bcl-2/HDAC dual-target inhibitors were designed and synthesized. Among them, compounds 7e–7g showed good inhibitory activities against HDAC6 and high binding affinities to Bcl-2 protein simultaneously. They also displayed good growth inhibitory activities against human MM cell line RPMI-8226, which proved their potential value for the treatment of multiple myeloma.

An amplified synthesis method of 3-nitro-4-halogeno-benzenesulfonamide is disclosed. According to the method, 4-halogeno-benzenesulfonyl chloride which is used as a raw material undergoes nitration to prepare 3-nitro-4-halogeno-benzenesulfonyl chloride; and after aminolysis, 3-nitro-4-halogeno-benzenesulfonamide is prepared. By the synthesis method provided by the invention, the synthesis route by the adoption of chlorosulfonic acid is changed, and production safety is remarkably raised. The reaction condition is milder and is easy for production control. Thus, mass production of the compound is easier to implement and realize.

The anti-apoptotic Bcl-2 proteins are attractive targets for anti-cancer drug development, and the discovery of their selective inhibitors has become a research focus. In this Letter, obvious differences in the P1 pocket of the active site between Bcl-2, Bcl-xL, and Mcl-1 proteins were proposed by the structural comparison of these proteins. As a result, the groups in their inhibitors binding to the P1 pockets may have significant effect on the selectivity for these proteins. Based on this hypothesis, five types of derivatives of the lead compound B-1 were designed, and several highly selective inhibitors of Bcl-xL(E-1) or Mcl-1 proteins (G) were found. The selective inhibitors of Mcl-1 protein found in this Letter provide new structural types for the development of novel antitumor agents.
