Antitumor-promoting naphthoquinones from Catalpa ovata.[Pubmed:9599262]
J Nat Prod. 1998 May;61(5):629-32.
Bioassay-directed fractionation of an extract of the stem-bark of Catalpa ovata led to the isolation of three new naphthoquinones: 8-methoxydehydroiso-alpha-lapachone (1), 9-methoxy-4-oxo-alpha-lapachone (2), and (4S,4aR,10R,10aR)-4, 10-dihydroxy-2,2-dimethyl-2,3,4,4alpha,10, 10alpha-hexahydrobenzo[g]chromen-5-one (3), which is a 1,4-reductive form of 6. The known compounds 3-hydroxydehydroiso-alpha-lapachone (4), 4,9-dihydroxy-alpha-lapachone (5), 4-hydroxy-alpha-lapachone (6), and 9-methoxy-alpha-lapachone (7), and Catalpalactone (8) were also isolated. Their structures were elucidated by spectral methods. These compounds all exhibited significant inhibitory activity against 12-O-tetradecanoylphorbol 13-acetate (TPA)-induced Epstein-Barr virus early antigen (EBV-EA) activation in Raji cells.
Major antitermitic components of the heartwood of southern catalpa.[Pubmed:24254942]
J Chem Ecol. 1992 Mar;18(3):359-69.
The heartwood of southern catalpa,Catalpa bignonioides Walt., is resistant to attack by the eastern subterranean termiteReticulitermes flavipes (Kollar), but extraction with a ternary solvent mixture of acetone-hexanewater (54ratio44ratio2) by volume removed the antitermitic characteristics from the heartwood. Four compounds comprised approximately 98% of the antitermitic fraction of the extract: the sesquiterpene alcohol, catalponol (67%); its epimer, epicatalponol (5%); a structurally related ketone, catalponone (1%); and the phthalide, Catalpalactone (25%). Pure compounds were isolated by semipreparative scale reversed-phase HPLC and identified by GC-MS and UV spectroscopy. The structure of catalponol was further confirmed by the formation of derivatives. Bioassays indicated that catalponol had the greatest toxicity in cellulose pad tests, but in tests using vacuum impregnation of these compounds into termite-susceptible wood blocks at levels approximating those found in catalpa heartwood, Catalpalactone exhibited the highest antitermitic activity.
Naphthoquinones from Catalpa ovata and their inhibitory effects on the production of nitric oxide.[Pubmed:20361302]
Arch Pharm Res. 2010 Mar;33(3):381-5.
Bioassay-guided fractionation of a CH2Cl2-soluble fraction of the stems of Catalpa ovata led to isolation of a new naphthoquinone, 4-hydroxy-2-(2-methoxy-3-hydroxy-3-methyl-but-1-enyl)-4-hydro-1H-naphthalen-1-one (10), together with nine known compounds, catalponol (1), catalponone (2), Catalpalactone (3), alpha-lapachone (4), 9-hydroxy-alpha-lapachone (5), 4,9-dihydroxy-alpha-lapachone (6), 9-methoxy-alpha-lapachone (7), 4-oxo-alpha-lapachone (8), and 9-methoxy-4-oxo-alpha-lapachone (9). The structures were elucidated on the basis of spectroscopic analyses. The inhibitory effects of these isolates on lipopolysaccharide-induced NO synthesis in RAW 264.7 cells were evaluated. Among them, catapalactone (3), 9-hydroxy-alpha-lapachone (5) and 4,9-dihydroxy-alpha-lapachone (6) exhibited potent inhibitory effects, with IC(50) values of 9.80, 4.64 and 2.73 microM, respectively.
Effects of catalpalactone on dopamine biosynthesis and L-DOPA-induced cytotoxicity in PC12 cells.[Pubmed:21783893]
Environ Toxicol Pharmacol. 2008 Jul;26(1):86-91.
The effects of Catalpalactone on dopamine biosynthesis and L-DOPA-induced cytotoxicity in PC12 cells were investigated. Catalpalactone at 5-30muM decreased intracellular dopamine content with the IC(50) value of 22.1muM. Catalpalactone at 5-20muM, but not 30muM, did not alter cell viability. Catalpalactone at 20muM inhibited tyrosine hydroxylase (TH) and aromatic-l-amino acid decarboxylase (AADC) activities. Catalpalactone also decreased cyclic AMP levels and inhibited TH phosphorylation. In addition, Catalpalactone at 20muM reduced the increases in dopamine levels induced by L-DOPA (20-50muM). Catalpalactone (5-30muM) associated with L-DOPA (50-100muM) enhanced L-DOPA-induced cytotoxicity at 48h, which was prevented by N-acetyl-l-cysteine. These results suggest that Catalpalactone inhibited dopamine biosynthesis by reducing TH and AADC activities and enhanced L-DOPA-induced cytotoxiciy in PC12 cells.
