Tetrahydropyrrolization of Resveratrol and Other Stilbenes Improves Inhibitory Effects on DNA Oxidation

The inhibitory effect of resveratrol on DNA oxidation caused by 2,2′-azobis(2-amidinopropane hydrochloride) (AAPH) was found to be enhanced if the C=C bond in resveratrol was converted into tetrahydropyrrole by reaction with azomethine ylide (CH2=N+(CH3)CH2?). This encouraged us to explore whether the inhibitory activities of other stilbenes could also be increased by the same method. We found that the inhibitory effects of the tetrahydropyrrole derivatives on AAPH-induced oxidation of DNA were higher than those of the corresponding stilbenes, because the tetrahydropyrrole motif can provide hydrogen atoms to be abstracted by radicals. Therefore, the tetrahydropyrrolization offered an advantage for enhancing the antioxidant effects of stilbenes. Notably, (CH3)3SiCH2N(CH3)CH2OCH3(in the presence of CF3COOH) and (CH3)3NO (in the presence of LiN(iPr)2) can be used to generate azomethine ylide for the tetrahydropyrrolization of stilbenes containing electron-withdrawing and -donating groups, respectively.

A facile two-step synthesis of 2-arylbenzofurans based on the selective cross McMurry couplings

(Chemical Equation Presented) A novel two-step synthesis of 2-arylbenzofurans has been developed. It involves a selective cross McMurry coupling of a salicylaldehyde or substituted salicylaldehyde with an aromatic aldehyde and a sequential oxidative cyclization of the resulting ortho-vinylphenols. Utilizing this synthetic protocol, a variety of 2-arylbenzofurans including cicerfuran (5) have been efficiently synthesized.

Syntheses and Platelet Aggregation Inhibitory and Antithrombotic Properties of ethyl>benzenes

A series of ethyl>benzene derivatives were synthesized and evaluated for their ability to inhibit collagen-induced platelet aggregation in vitro and to protect experimantal thrombosis in mice.The results showed that the compounds were in vitro inhibitors of collagen-induced platelet aggregation.Most of them were also effective in the mouse antithrombotic assay.The compounds were found to be potent antagonists to S2 serotonergic receptor, and good correlation (r = 0.85) between their S2 serotonergic receptor antagonism and their potency as platelet antiaggregatory drugs was observed.Among the compounds studied, monophenoxy>methyl>ethyl>succinate hydrochloride (12b, MCI-9042) was selected for further pharmacological and toxicological evaluation.

Substituted (ω-aminoalkoxy)stilbene derivatives as a new class of anticonvulsants

A series of substituted (ω-aminoalkoxy)stilbene derivatives has been synthesized and screened for anticonvulsant activity. The effect of structural modification of these molecules on the activities has been systematically examined. Potent anticonvulsant activity was displayed by 2-[4-(4-methyl-1-piperazinyl)butoxy]stilbene and some 2-[4-(3-alkoxy-1-piperidino)butoxy]stilbene derivatives, as determined by maximal electroshock seizure (MES) and pentylenetetrazol-induced convulsion tests in mice. One of these derivatives exhibited more potent anti-MES activity than diphenylhydantoin and carbamazepine in further pharmacological tests in rats, and its therapeutic index was superior to those of two antiepileptic drugs.
