The discovery of novel small molecule allosteric activators of aldehyde dehydrogenase 2.

Aldehyde dehydrogenase 2 (ALDH2) plays important role in ethanol metabolism, and also serves as an important shield from the damage occurring under oxidative stress. A special inactive variant was found carried by 35-45% of East Asians. The variant carriers have recently been found at the higher risk for the diseases related to the damage occurring under oxidative stress, such as cardiovascular and cerebrovascular diseases.

Synthesis and biological evaluation of 7-methoxy-1-(3,4,5-trimethoxyphenyl)-4,5-dihydro-2H-benzo[e]indazoles as new colchicine site inhibitors.

The colchicine site inhibitors (CSIs) displayed both antimitotic and vascular disrupting activities, therefore are promising potential antitumor agents. In this study, a series 1-phenyl-4,5-dihydro-2H-benzo[e]indazoles were found as new CSIs of which the bioactive configuration was locked. Among them, compounds C1 and C2 displayed the best activity, with tubulin polymerization IC of 3.

1-Phenyl-dihydrobenzoindazoles as novel colchicine site inhibitors: Structural basis and antitumor efficacy.

The colchicine site inhibitors (CSIs) showed promising prospects as antitumor agents due to their vascular disrupting activities besides antimitotic activities. 1-Phenyl-dihydrobenzoindazole was found as a novel scaffold of CSI without the cis-trans isomerization problem. The X-ray co-crystal structure of the lead compound with tubulin was determined, which revealed the binding mode including special water-bridged hydrogen bonds.

Design, synthesis, and bioactivity evaluation of novel Bcl-2/HDAC dual-target inhibitors for the treatment of multiple myeloma.

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.
