Two new 9-hydroxy-7H-furo[3,2-g]chromen-7-one derivatives were designed, synthesized and evaluated for their in vitro vasodilatory activity. The structures of two compounds were elucidated by infrared, 1H NMR, and mass spectral data. The invitro pharmacological evaluation indicated that both of them possessed well vasodilatory activity compared with imperatorin. The molecule docking also showed two target compounds docked well with L-calcium channel (PDB code: 3G43). The result suggested that they would be potential vasodilatory agents for hypertension.

New verapamil analogues were synthesized and their inhibitory activities against Mycobacterium tuberculosis H37Rv determined in vitro alone and in combination with rifampicin (RIF). Some analogues showed comparable activity to verapamil and exhibited better synergies with RIF. Molecular docking studies of the binding sites of Rv1258c, a M. tuberculosis efflux protein previously implicated in intrinsic resistance to RIF, suggested a potential rationale for the superior synergistic interactions observed with some analogues.

A hair growth promoting composition comprising, as an effective ingredient, a phenylacetonitrile derivative or a pharmacologically acceptable salt thereof expressed by the following Formula (I): wherein each of R1 and R2 is hydrogen atom, a C1-10 alkyl group, a C2-10 alkenyl group or C2-10 acyl group, or NR1R2 may be a heterocycle having 3-7 members; R3 is a C1-5 alkyl group; and each of R4, R5 and R6 is hydrogen atom or a C1-4 alkoxy group. The present invention provides a hair growth promoting composition having excellent effects on promoting hair regrowth, preventing or inhibiting hair loss, and the like in human by compounding above-specified phenylacetonitrile derivative as a effective ingredient thereto.

, p. 351 - 359 (2007/10/02)
In the verapamil structure, the 3,4-dimethoxy phenylethyl group has been replaced by several moieties belonging to α- and β-blockers or other classes of calcium channel blockers.The best derivatives, as calcium blockers, were prepared with β-blocker fragments like aryloxypropanolamines (AOPA) with an ortho substituent on the aromatic ring.
