  Six known beta-carboline, dihydro-beta-carboline, and tetrahydro-beta-carboline alkaloids and a series of their derivatives were designed, synthesized, and evaluated for their anti-tobacco mosaic virus (TMV) and fungicidal activities for the first time. All of the alkaloids and some of their derivatives (compounds 3, 4, 14, and 19) exhibited higher anti-TMV activity than the commercial antiviral agent Ribavirin both in vitro and in vivo. Especially, the inactivation, curative, and protection activities of alkaloids Harmalan (62.3, 55.1, and 60.3% at 500 mu g/mL) and tetrahydroharmane (64.2, 57.2, and 59.5% at 500 mu g/mL) in vivo were much higher than those of Ribavirin (37.4, 36.2, and 38.5% at 500 mu g/mL). A new derivative, 14, with optimized physicochemical properties, obviously exhibited higher activities in vivo (50.4, 43.9, and 47.9% at 500 mu g/mL) than Ribavirin and other derivatives; therefore, 14 can be used as a new lead structure for the development of anti-TMV drugs. Moreover, most of these compounds exhibited good fungicidal activity against 14 kinds of fungi, especially compounds 4, 7, and 11.

  In a continuing effort to develop novel beta-carbolines endowed with better pharmacological profiles, a series of beta-carboline derivatives were designed and synthesized based on the previously developed SARs. Cytotoxicities in vitro of these compounds against a panel of human tumor cell lines were also investigated. The results demonstrated that the N(2)-benzylated beta-carbolinium bromides 56-60 represented the most potent compounds with IC(50) values lower than 10 mu M. The application of 3D-QSAR to these compounds explored the structural basis for their biological activities. CoMFA (q(2) = 0.513, r(2) = 0.862) and CoMSIA (q(2) = 0.503, r(2) = 0.831) models were developed for a set of 47 beta-carbolines. The results indicated that the antitumor pharmacophore of these molecules were marked at position-1, -2, -3, -7 and -9 of beta-carboline ring.
