We report a new molecular design for optically triggered nm-scale translation of a submolecular component relative to another. We used a rotaxane-like molecule terminated at one end with stiff stilbene that served both as a chromophore to trigger the tran

- Design, synthesis, docking studies and biological evaluation of novel dihydro-1,3,5-triazines as human DHFR inhibitors
-
A novel series of dihydro-1,3,5-triazine derivatives bearing a heteroatom spiro-ring were designed and synthesized on the basis of molecular flexible docking work, and their biological activities were evaluated. Compounds A2, A5, B1 and B3 showed potent human dihydrofolate reductase (hDHFR) inhibitory activity with IC50values of 7.46 nM, 3.72 nM, 6.46 nM, 4.08 nM, versus reference drug methotrexate (MTX). From the molecular docking result we concluded that the conformation space generated by deformation of the flexible residue Phe31 is favorable for the binding of the spiro-ring, and inserting heteroatom into spiro ring might increase the binding affinity. There were 24 compounds with broadspectrum antiproliferative activity against several tumor cell lines (HCT116, A549, HL-60, HepG2 and MDA-MB-231) with IC50values ranging from 0.79 to 0.001 μM. The antitumor activity in?vivo of compound A2 was determined in a human alveolar basal epithelial cell line A549 xenograft model. This study offered novel anticancer agents with high inhibitory activity that target hDHFR and have a binding mode of the novel molecular scaffold with hDHFR. This provides potent support for further development of novel hDHFR inhibitors.

- Discovery and structure-activity relationship studies of N-substituted indole derivatives as novel Mcl-1 inhibitors
-
Myeloid cell leukemia-1 (Mcl-1) is an important antiapoptotic protein functioning through protein-protein interactions. We discovered LSL-A6 (2-((2-carbamoyl-1-(3-(4-methoxyphenoxy)propyl)-1H-indol-6-yl)oxy)acetic acid) with a novel N-substituted indole scaffold to interfere Mcl-1 binding as a novel Mcl-1 inhibitor. Molecular modeling indicated that this compound binds with Mcl-1 by interaction with P2 and R263 hot-spots. Structure modification focused on several moieties including indole core, hydrophobic tail and acidic chain were conducted and structure-activity relationship was analyzed. The most potent compound 24d which exhibited Ki value of 110?nM for interfering Mcl-1 binding was obtained after hit-to-lead modification.

- ANTIDIABETIC TRICYCLIC COMPOUNDS
-
Novel compounds of the structural formula (I), and the pharmaceutically acceptable salts thereof, are agonists of G-protein coupled receptor 40 (GPR40) and may be useful in the treatment, prevention and suppression of diseases mediated by the G-protein-coupled receptor 40. The compounds of the present invention may be useful in the treatment of Type 2 diabetes mellitus, and of conditions that are often associated with this disease, including obesity and lipid disorders, such as mixed or diabetic dyslipidemia, hyperlipidemia, hypercholesterolemia, and hypertriglyceridemia.
