A bio-inspired synthesis of hybrid flavonoids from 2-hydroxychalcone driven by visible light

A bio-inspired synthesis of hybrid flavonoids from 2-hydroxylchalcone is described. Under the irradiation of 24 W CFL, 2-hydroxychalcone reacts with various nucleophiles to deliver structurally diverse hybrid flavonoids in good to excellent yields in the presence of a catalytic Br¡ãnsted acid. Moreover, moderate enantioselectivities could be obtained using a catalytic chiral phosphoric acid via counter anion directed addition. Based on mechanistic studies, the reaction is proposed to proceed via tandem double-bond isomerization/dehydrated cyclization of 2-hydroxychalcone to form a transient flavylium cation, which is in situ captured by nucleophiles to afford hybrid flavonoids.

O-alkylhydroxylamines as rationally-designed mechanism-based inhibitors of indoleamine 2,3-dioxygenase-1

Indoleamine 2,3-dioxygenase-1 (IDO1) is a promising therapeutic target for the treatment of cancer, chronic viral infections, and other diseases characterized by pathological immune suppression. Recently important advances have been made in understanding IDO1’s catalytic mechanism. Although much remains to be discovered, there is strong evidence that the mechanism proceeds through a heme-iron bound alkylperoxy transition or intermediate state. Accordingly, we explored stable structural mimics of the alkylperoxy species and provide evidence that such structures do mimic the alkylperoxy transition or intermediate state. We discovered that O-benzylhydroxylamine, a commercially available compound, is a potent sub-micromolar inhibitor of IDO1. Structure-activity studies of over forty derivatives of O-benzylhydroxylamine led to further improvement in inhibitor potency, particularly with the addition of halogen atoms to the meta position of the aromatic ring. The most potent derivatives and the lead, O-benzylhydroxylamine, have high ligand efficiency values, which are considered an important criterion for successful drug development. Notably, two of the most potent compounds demonstrated nanomolar-level cell-based potency and limited toxicity. The combination of the simplicity of the structures of these compounds and their excellent cellular activity makes them quite attractive for biological exploration of IDO1 function and antitumor therapeutic applications.

Solubility, thermodynamic modeling and Hansen solubility parameter of 5-norbornene-2,3-dicarboximide in three binary solvents (methanol, ethanol, ethyl acetate + DMF) from 278.15 K to 323.15 K

In this work, solubility of 5-norbornene-2,3-dicarboximide (NODI) in three binary solvents (DMF + methanol, ethanol, ethyl acetate) was experimentally investigated by using laser monitoring technique at (278.15 to 323.15) K under 0.1 MPa. Solubility data of NODI increased as the temperature increased while reduced with the decreasing mass fraction of DMF. Hansen solubility parameter was employed to reveal the solubility behavior of NODI. Experimental solubility data was correlated by five thermodynamic models including NRTL, Wilson, uniquac, Margules and Jouyban-Acree-modified Apelblat (J-A-A) model. The Wilson, Margules, and uniquac model were more suitable to correlate NODI solubility than others. Besides, thermodynamic properties of mixing process (DeltamixG, DeltamixS, DeltamixH, H1 E,?, lngamma1 and lngamma1 ?) were investigated based on solubility data and the Wilson equation. Mixing processes of NODI in three binary solvents were entropy-driven.
