Naamines and naamidines as novel agents against a plant virus and phytopathogenic fungi

Naamines, naamidines and various derivatives of these marine natural products were synthesized and characterized by means of nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry. The activities of these alkaloids against a plant virus and phytopathogenic fungi were evaluated for the first time. A benzyloxy naamine derivative 15d displayed excellent in vivo activity against tobacco mosaic virus at 500 μg/mL (inactivation activity, 46%; curative activity, 49%; and protective activity, 41%); its activities were higher than the corresponding activities of the commercial plant virucide ribavirin (32%, 35%, and 34%, respectively), making it a promising new lead compound for antiviral research. In vitro assays revealed that the test compounds exhibited very good antifungal activity against 14 kinds of phytopathogenic fungi. Again, the benzyloxy naamine derivative 15d exhibited broad-spectrum fungicidal activity, emerging as a new lead compound for fungicidal research. Additional in vivo assays indicated that many of the compounds displayed inhibitory effects >30%.

Naamine derivatives, preparation method of Nammine derivatives, and application of Nammine derivatives in treatment of plant viruses and bacterial diseases

The invention discloses Naamine derivatives, a preparation method of the Nammine derivatives, and an application of the Nammine derivatives in treatment of plant viruses and bacterial diseases. The Nammine derivatives specifically are compounds represented as formulae from I-1 to I-16. During each reaction, materials participating in the reaction are taken according to the molar ratio required bythe reaction; excess substances are selected to participate in the reaction so as to ensure the reaction process of a target product; the pH value and reacting temperature and time of a system are determined according to the reaction type; and purifying separation or drying is carried out after the preparation. The Naamine derivatives provided by the invention exhibit good activity for treating plant viruses and bacterial diseases, and can well inhibit the following 14 species of plant pathogenic bacteria: tobacco mosaic virus (TMV), Fusarium oxysporum (Schl.)F.sp cucumerinum Owen, cercosporaarachidicola, Botryospuaeria berengeriana, Rhizotonia cerealis van der Hoeven apud.Boerema & Verhoeven, Helminthosporium maydis Nisik & Miy, Colleetotrichum lagenarium (Pass.) Ell. et Halst, fusariummoniliforme, Alternaria solani, FusaHum graminearum, Phytophthora infestans, phytophthora capsici, sclerotinia sclerotiorum, Botrytis cinerea and Thanatephorus cucumeris.

PRODRUGS OF OXAZOLIDINONE CETP INHIBITORS

The compounds of Formula I are prodrugs of CETP inhibitors having a central oxazolidinone ring. The compounds cyclize by the elimination of HX to form an oxazolidinone ring after administration to a patient.
