Pyridine alkaloids from a Parthenium hybrid.
نویسندگان
چکیده
Two pyridine alkaloids were isolated from the derubberized resin of the hybrid Parthenium argentatum x P tomentosa. These alkaloids are (+/-)-N-[4-(1-aminoethyl) phenyl]-4-[3-methylbutenylidine]-1,4-dihydropyridine (guayulamine A) and (+/-)-N-[4-(1-aminoethyl) phenyl]-4-[4-methylpentenylidine]-1, 4-dihydropyridine (guayulamine B). The structures were established by one- and two-dimensional NMR spectroscopy and mass spectrometry.

Assessment of Phytochemical screening and Antifungal Activity of Parthenium hysterophrous L
Phytochemical screening and Antifungal activities of Parthenium hysterophrous L (Asteraceae) was carried out in laboratory. Distilled water and methanol extracts of the leaves of plant was prepared. Five phytopathogenic fungi: Alternaria brassicae, Botrytis cinerea, Fusarium oxysporum, Phytophthora capsici and Sclerotium rolfsii were tested at different concentrations (50 mg/ml, 100 mg/ml, 150 ...
متن کاملNew pyridine alkaloids from rove beetles of the genus Stenus (Coleoptera: Staphylinidae).
Three new pyridine alkaloids were detected in the pygidial glands of some Stenus species. The chemotaxonomic significance of the occurrence of these alkaloids and stenusine in different Stenus species is discussed. The antimicrobial properties of (Z)- and (E)-3-(2-methyl-1-butenyl)-pyridine and the deterrent activities of stenusine and norstenusine were investigated.

Reaction of tryptamine 1 with dimethyl -3-methoxyallylidenemalonate 2 afforded N?-[4,4-bis (methoxycarbonyl)-1,3-butadienyl] tryptamine 3 which in combination with acetylchloride and pyridine in dichloromethane gave N?, N?-[acetyl]-[(4,4-dinethoxycarbonyl) 1,3butadienyl] tryptamine 4. Treatment of 3 with sodium hydroxide afforded 2H[N-(3-indolyl) ethyl] 2-oxo-3-methoxycarbonyl-1-pyridine 5. Cy...
متن کاملMonasnicotinates A-D, four new pyridine alkaloids from the fungal strain Monascus pilosus BCRC 38093.
Four new pyridine derivatives, monasnicotinates A-D (1-4) were isolated from the red yeast rice of Monascus pilosus BCRC 38093. Their structures were elucidated on the basis of physicochemical evidence, in-depth NMR spectroscopic analysis, and high-resolution mass spectrometry. Their inhibitory effects on NO production was also evaluated.
متن کاملThe co-occurrence of two pyridine alkaloids, mimosine and trigonelline, in Leucaena leucocephala.
Leucaena leucocephala is a nitrogen-fixing tropical leguminous tree that produces two pyridine alkaloids, i. e. mimosine [beta-(3-hydroxy-4-pyridon-1-yl)-L-alanine] and trigonelline (1-methylpyridinium-3-carboxylate). Mimosine has been detected in leaves, flowers, pods, seeds, and roots, and it is one of the principal non-protein amino acids that occurs in all organs. Asparagine was the most ab...
