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

Paragraph 0035, (2018/05/16)
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.
Development of Novel Monoamine Oxidase-B (MAO-B) Inhibitors with Reduced Blood-Brain Barrier Permeability for the Potential Management of Noncentral Nervous System (CNS) Diseases
Gealageas, Ronan,Devineau, Alice,So, Pauline P. L.,Kim, Catrina M. J.,Surendradoss, Jayakumar,Buchwalder, Christian,Heller, Markus,Goebeler, Verena,Dullaghan, Edith M.,Grierson, David S.,Putnins, Edward E.

Studies indicate that MAO-B is induced in peripheral inflammatory diseases. To target peripheral tissues using MAO-B inhibitors that do not permeate the blood-brain barrier (BBB) the MAO-B-selective inhibitor deprenyl was remodeled by replacing the terminal acetylene with a CO2H function, and incorporating a para-OCH2Ar motif (compounds 10a-s). Further, in compound 32 the C-2 side chain corresponded to CH2CN. In vitro, 10c, 10j, 10k, and 32 were identified as potent reversible MAO-B inhibitors, and all four compounds were more stable than deprenyl in plasma, liver microsomal, and hepatocyte stability assays. In vivo, they demonstrated greater plasma bioavailability. Assessment of in vitro BBB permeability showed that compound 10k is a P-glycoprotein (P-gp) substrate and 10j displayed mild interaction. Importantly, compounds 10c, 10j, 10k, and 32 displayed significantly reduced BBB permeability after intravenous, subcutaneous, and oral administration. These polar MAO-B inhibitors are pertinent leads for evaluation of efficacy in noncentral nervous system (CNS) inflammatory disease models.
An expeditious synthesis of the ascomycete metabolite rigidiusculamide B
Wunder, Anja,Schobert, Rainer
, p. 9262 - 9266 (2016/10/13)
The ascomycete metabolite rigidiusculamide B was synthesised in six steps and 22% overall yield. The key steps were a Li2Te-triggered Dittmer-type Dieckmann cyclisation of an N-(α-haloacyl)tyrosine ester to give a 4-O-silyl tetramate, followed

Reddy, G. Vidyasagar,Iyengar
, p. 299 - 300 (2007/10/03)
A two step strategy for optically pure N-Protected-N-methyl-α-amino acids starting from N-protected-α-amino acids via reductive cleavage of oxazolidinones using NaCNBH3/TMSCl is described.
Synthesis of (9R,12S)- and (9S,12S)-cycloisodityrosine and their N-methyl derivatives
Boger, Dale L.,Zhou, Jiacheng,Borzilleri, Robert M.,Nukui, Seiji,Castle, Steven L.
, p. 2054 - 2069 (2007/10/03)
Full details of the synthesis of (9R,12S)- and (9S,12S)-cycloisodityrosine and their N-methyl derivatives are detailed based on an intramolecular nucleophilic aromatic substitution reaction for formation of the key biaryl ether with 14-membered ring macrocyclization. Their comparison with prior samples and the documentation of a facile C9 epimerization within the natural 9S series are described.
SYNTHESIS OF CYCLO-N-METHYL-L-TYR-N-METHYL-L-TYR-D-ALA-L-ALA-O,N-DIMETHYL-L-TYR-L-ALA, A CYCLIC HEXAPEPTIDE RELATED TO THE ANTITUMOR AGENT DEOXYBOUVARDIN

, p. 785 - 790 (2007/10/02)
A synthesis of the title cyclic hexapeptide is described.Its lack of antitumor activity shows that the 14-membered ring of deoxybouvardin is needed for activity.Efforts to oxidatively its phenolic groups failed to give deoxybouvardin.
