Solutions of biologically active substances insoluble in water (thiosulfoesters, anthraquinone derivatives, pyrazoline) were obtained using a combined solvent and biogenic surfactants. For this purpose used rhamnolipids, their biocomplex with polysaccharides synthesized by the Pseudomonas SP strain. PS-17, trehalosolipids Rhodococcus erythropolis AU-1 strain, commercial biosurfactant surfactant...

Bulgarian medicinal plants, which have been studied during the last years, are reviewed. The review includes the following families: Amaryllidaceae, Asteraceae, Berberidaceae, Boraginaceae, Fabaceae, Geraniaceae, Lamiaceae, Oleaceae, Onagraceae, Scrophulariaceae, Solanaceae, Ranunculaceae, Rosaceae, Rutaceae, Valerianaceae, Zygophyllaceae. Main pharmacological properties are antiviral, antimicr...

Kojic acid (5-hydroxy-2-hydroxymethyl-4-pyranone) represents an attractive polyfunctional skeleton for development of biologically active compounds. The authors prepared a great variety of kojic acid derivatives and selected biological properties have been studied. Thus, kojic acid derivatives are promising compounds that might advantageously be used in human and/or veterinary medicine and also...

Introduction A vast number of heterocyclic moieties are used in pharmaceutical research, agricultural science and drug discovery. Heterocyclic building blocks also have practical use as components in dyestuffs, antioxidants, copolymers, bases and ligands. Nitro heterocyclic compounds have diverse biological activity, antiinflammatory or vasodilator activity and structure activity relationship, ...

Pomegranate is a widely used plant having medicinal properties. In this review, we have mainly focused on the already published data from our laboratory pertaining to the effect of methanol extract of pericarp of pomegranate (PME) and have compared it with other relevant literatures on Punica. Earlier, we had shown its antiproliferative effect using human breast (MCF-7, MDA MB-231), and endomet...

Bryophytes are known to produce a great range of biologically active compounds viz. terpenoids, aromatic compounds, and acetogenins. A lot of these constituents have typical odour, tanginess, and bitterness, and exhibit a fairly curious collection of bioactivities and medicinal properties. Chemical studies of the bryophytes were neglected for a long time in India. They are stockroom of naturall...
