Benzalcyanoacetamides were designed and synthesized as reversible thiol conjugate addition acceptors. These thia-conjugate additions can rapidly and reversibly achieve equilibrium under aqueous conditions at neutral pH. Kinetic studies show that electron-withdrawing groups at the 4-position of the phenyl ring of the benzalcyanoacetamides promote the conjugate addition at equilibrium. Dynamic thiol exchange of these conjugate acceptors is faster than singly activated α,β-unsaturated carbonyl compounds. These thia-conjugate additions can be assembled as potentially useful components in dynamic combinatorial chemistry. Benzalcyanoacetamides were studied with thiols as reversible thiol conjugate addition acceptors. These thia-conjugate additions can rapidly and reversibly achieve equilibrium under aqueous conditions at neutral pH, which verifies the ultimate use of these conjugate acceptors in dynamic combinatorial chemistry.

Myeloid cell leukemia 1 (Mcl-1) protein is a key negative regulator of apoptosis, and developing Mcl-1 inhibitors has been an attractive strategy for cancer therapy. Herein, we describe the rational design, synthesis, and structure-activity relationship study of 3,5-dimethyl-4-sulfonyl-1H-pyrrole-based compounds as Mcl-1 inhibitors. Stepwise optimizations of hit compound 11 with primary Mcl-1 inhibition (52%@30 μM) led to the discovery of the most potent compound 40 with high affinity (Kd = 0.23 nM) and superior selectivity over other Bcl-2 family proteins (>40,000 folds). Mechanistic studies revealed that 40 could activate the apoptosis signal pathway in an Mcl-1-dependent manner. 40 exhibited favorable physicochemical properties and pharmacokinetic profiles (F% = 41.3%). Furthermore, oral administration of 40 was well tolerated to effectively inhibit tumor growth (T/C = 37.3%) in MV4-11 xenograft models. Collectively, these findings implicate that compound 40 is a promising antitumor agent that deserves further preclinical evaluations.

The invention belongs to the field of synthesis of organic intermediates, and specifically discloses an ultrasonic-assisted synthesis method for a benzoic acid compound. The method comprises the following step: promoting air oxidation of benzyl alcohol by using diethylene glycol dimethyl ether under an ultrasonic-assisted action so as to obtain the benzoic acid compound, wherein a benzyl alcohol raw material is benzyl alcohol, or a benzoic acid derivative containing one to five substituents at different positions on the benzene ring of benzyl alcohol; and a reaction accelerator is the diethylene glycol dimethyl ether. The method provided by the invention has the advantages of easily-available raw materials, simple and convenient reaction conditions, short reaction time, greenness, energy conservation, high reaction selectivity and yield, excellent compatibility of substrate functional groups, and high application value.
