New chiral camphane-derived benzisoselenazol-3(2H)-ones and corresponding diselenides have been synthetized using a convenient one-pot procedure. Se-N bond was efficiently converted to an Se-Se bond, which could also be easily re-oxidized to the initial benzisoselenazolone moiety. The antioxidant activity of camphor derivatives was evaluated and compared to the reactivity of a series of N-amino...

conclusions the results of the present study indicate the protective effects of melissa officinalis on some sperm parameters and spermatogenesis quality in rats exposed to lead. background some medicinal plants with their antioxidant properties have protective effects on sperm parameters and neutralize the harmful effects of lead exposure. objectives the present study aimed to determine the eff...

differentiation among populations of the iranian teucrium polium l.was analyzed on the basis of morphological and phytochemical variability, to evaluate the level and distribution of diversity among four distant populations from arid, semi-arid, and sub-humid regions of fars province. morphological analysis included 11 characters related to the plant, leaf, and stem morphology. analyses of vari...

The title compound, C12H20N4O, undergoes a phase transition on cooling. The room-temperature structure is tetra-gonal (P43212, Z' = 1), with the meth-oxy-bornyl group being extremely disordered. Below 213 K the structure is ortho-rhom-bic (P212121, Z' = 2), with ordered mol-ecules. The two independent mol-ecules (A and B) have very similar conformations; significant differences only occur for t...

Background & aim: Sage (Salvia officinalis L.) is a perennial medicinal herb which belongs to Lamiales order and Lamiaceae family. This plant has economical value for four years. Nowadays the use of plant growth regulators (PGR) has an important role for increasing the secondary metabolites in plants. Among PGRs Jasmonic (JA) and salicylic acid (SA) have many applications in medicinal ...

Acyclic asymmetric quaternary stereocenters, which are composed of four carbon-carbon bonds, were finely constructed by utilizing a face-selective alkylation enolate intermediates derived from an Michael addition reaction chiral lithium amide with trisubstituted (E)-α,β-unsaturated esters. The present was able to employ diverse alkyl halides as electrophile afford various adducts having all-car...
