Based on our previous structure-activity relationship and antiviral mechanism studies, a series of 14-aminophenanthroindolizidines (1a-i, 2, and 3) were designed, targeting tobacco mosaic virus (TMV) RNA, and synthesized and systematically evaluated for their antiviral activity against TMV. The bioassay results showed that most of these compounds exhibited good to excellent in vivo anti-TMV activity, of which compounds 1d and 1h displayed significantly higher activity than commercial ningnanmycin, and thus emerged as potential inhibitors of plant virus. The introduction of amino groups at the 14-position of phenanthroindolizidines, which is proposed to interact with arginine residues around the TMV RNA, increased anti-TMV activity.

    ABSTRACT: Glycoconjugates of phenanthroindolizidine alkaloids targeting tobacco mosaic virus (TMV) RNA were designed, synthesized, and evaluated for their antiviral activity against TMV for the first time. The glycoconjugation of [Formula: see text]-6-O-desmethylantofine (2) and 14-hydroxyltylophorines (3-6) was accomplished in three ways (O-glycosylation manner, using carbamoyloxy as linker arm, and using 1,2,3-triazole as linker arm) with three different sugar units (glucose, galactose, and mannose). The glycoconjugates showed improved water solubility and molecule polarity compared with phenanthroindolizidine alkaloids. The bioassay results showed that C6 was a suitable position for glycoconjugation and O-glycosylation can increase the antiviral activity of phenanthroindolizidine alkaloids indicating that the introduction of sugar units can improve the antiviral activity profile of glycoconjugates. Two O-glycosides of [Formula: see text]-6-O-desmethylantofine, (13aS)-6-O-[Formula: see text]-D-galactopyranosyl-2,3-dimethoxyphenanthro [9,10-b]-11-indolizidinone (10) and (13aS)-6-O-[Formula: see text]-D-mannopyranosyl-2,3-dimethoxyphenanthro [9,10-b]-11-indolizidinone (11) displayed significant higher activity than commercial ningnanmycin, and thus could be considered for novel therapy against plant virus infection.

    ABSTRACT: Phenanthroindolizidine alkaloids are a well-known class of compounds due to their interesting biological activities, especially anticancer ones. Represented by more than 60 substances, they are mainly isolated from plants of the Moraceae and Asclepiadaceae families. In the last 30 years, a great effort has been made aiming the synthesis of these compounds and analogues to be applied in medicinal chemistry. This short review will highlight recent contributions in the synthesis of these compounds, covering the years 2009-2012.

    ABSTRACT: To investigate the influence of the variation of the original skeletons of naturalphenanthroindo/quinolizidine alkaloids on the antiviral activities, two types of structurally totally novel analogues 7a, 7b, 16a, and 16b were designed, synthesized, and evaluated for their antiviral activity against tobacco mosaic virus (TMV) for the first time. Bioassay results indicated that all of the four new designed analogues showed good to excellent antiviral activities, among which analogue 16a dispalyed comparable activity with that of Ningnanmycin, perhaps one of the most successful commercial antiviral agent, thus emerging as a potential inhibitor of plant virus and can serve as a new lead for further optimization. Further structure-activity relationships are also discussed, demonstrating for the first time that same changes of the orginal sketons of phenanthroindolizidine and phenanthroquinolizidine exihibted totally different antiviral activities results, providing some original and useful information about the preferential conformation for keeping high activities.
