In the title compound, C(15)H(10)FNO(3), the dihedral angle between the isoindoline-1,3-dione and 3-fluoro-4-methyl-phenol groups is 86.88 (8)°. The isoindoline-1,3-dione fragment is almost planar, with an r.m.s. deviation of 0.0154 Å within the group. Inter-molecular C-H⋯O hydrogen bonds generate C(6) chains running parallel to the [010] direction.
A set of seventy four molecules belonging to the class of thioglitazones were subjected to the QSAR analysis for their antihyperglycemic activity. All the molecules were subjected to energy minimization to get 3D structures, followed by conformational analysis to get the conformation of the molecule associated with the least energy and highest stability. Various physico-chemical parameters were...
Technical iodine was found to catalyze the condensation between 2-aminobenzohydrazide (1) and some aldehydes and ketones in absolute ethanol under mild conditions to afford hydrazone and quinazoline derivatives, respectively. Condensation of 1 with terephthalaldehyde (2) in 1 : 1 molar ratios afforded the hydrazone 3, while hydrazone 4 was formed on using a double molar ratio of 1. On the other...
Two new ursane-type triterpenoids, 3β,19α,23-trihydroxyurs-12-en-24-al-28-oic acid (1) and 3β,19α,24-trihydroxy-23-norurs-12-en-28-oic acid (2), two new pregnane derivatives, 3β,12β-dihydroxy-5α-pregnane-14,16-dien-20-one (9) and 12β-hydroxy-5α-pregnane-14,16-dien-3,20-dione (10), and eight known compounds were isolated from the twigs and leaves of Emmenopterys henryi. The structures of the new...
To ascertain the exact anti-myeloma mechanism of thalidomide in vivo, we performed structural development studies of thalidomide, and obtained various analogues with specific molecular properties. Among these derivatives, we found that a new thalidomide analogue, 2-(2,6-diisopropylphenyl)-5-hydroxy-1H-isoindole-1,3-dione (5HPP-33) had the most potent anti-myeloma effect and tubulin-polymerizati...
Mesomorphous butterfly-like shape molecules based on benzodithiophene, benzodithiophene-4,8-dione and cyclopentadithiophen-4-one core moieties were efficiently synthesized by the Suzuki-Miyaura coupling Scholl oxidative cyclo-dehydrogenation reactions’ tandem. Most of butterfly spontaneously self-organize into columnar hexagonal mesophase. The electron-deficient systems possess strong solvent-g...
