Pithecellobium

This enzyme was recently purified from Streptococcus anginosus and the encoding gene, led, was cloned and characterized.7 H2S is also produced by roots of Acacia x giraffae Willd. and Pithecellobium elegans Ducke and occasionally by roots of other Acacia species.8... [Pg.673]

Reports on the antiviral activity of flavanones isolated from medicinal plants have also been found in the literature. Two new antiviral flavanone derivatives were isolated from a methanol extract of leaves of Pithecellobium clypearia (Jack.) Benth (Fabaceae), guided by antiviral assays.The structures were characterized as 7-0-galloyltricetifavan (Fig. 14) and 7,4 -di-0-galloyltricetifavan. CPE reduction assay showed that both compounds possess antiviral activity against respiratory syncytial virus, influenza A HlNl virus, CVB3 and HSV-1. Examples of other... [Pg.458]

The structures of the di- and trimeric profisetinidins from Pithecellobium dulce (Guamii-chil) were rigorously corroborated via synthesis.The synthetic approach was additionally motivated by the precariousness of unequivocally differentiating between 2,3-cis-3,4-trans-and 2,3-c7.s-3,4-c7.s-confugurations of the chain-extension units on the basis of H NMR coupling constants.Furthermore, the powerful nuclear Overhauser effect (NOE) method for differentiating between 2,4-cis- and 2,4-tra i -substitution is less useful at the di- and trimeric levels due to the adverse effects of dynamic rotational isomerism about the interflavanyl bond(s) on NMR spectra at ambient temperatures. [Pg.576]

The sulfiir-containing amino acid, djenkolic acid (82), is found in seeds of many species of Pithecellobium, Acacia, and Mimosa (Fig. 13.16). This compound produces human toxicity in Java when the seeds of P. lobatum are eaten. Related sulfiir-containing amino acids are found in these and other mimosoid legumes. [Pg.227]
