General Description

Sophorol is a natural glycolipid derived from yeast that has gained interest for its various potential applications in industries such as food, pharmaceuticals, and cosmetics. It is composed of a glucose molecule and a fatty acid, making it amphiphilic and capable of forming micelles in water. This makes it useful as a surfactant in various products. Sophorol also possesses antimicrobial properties, making it useful for preserving food and inhibiting the growth of harmful bacteria. Additionally, it has been studied for its potential as a drug delivery system and for its anti-inflammatory properties, making it a versatile and promising chemical for various industrial and biomedical applications.

(+)-Pisatin biosynthesis: From (-) enantiomeric intermediates via an achiral 7,2′-dihydroxy-4′,5′-methylenedioxyisoflav-3-ene

(+)-Pisatin, produced by peas (Pisum sativum L.), is an isoflavonoid derivative belonging to the pterocarpan family. It was the first chemically identified phytoalexin, and subsequent research has demonstrated that most legumes produce pterocarpans with the opposite stereochemistry. Studies on the biosynthesis of (+)-pisatin have shown that (-) enantiomeric compounds are intermediates in (+)-pisatin synthesis. However, the steps from the (-)-7,2′-dihydroxy-4′,5′-methylenedioxyisoflavanone [(-)-sophorol] intermediate to (+)-6a-hydroxymaackiain intermediate are undetermined. Chemical reduction of (-)-sophorol using sodium borohydride (NaBH4) produced two isomers of (-)-7,2′-dihydroxy-4′, 5′-methylenedioxyisoflavanol [(-)-DMDI] with optimal UV absorbance at 299.3 and 300.5 nm, respectively. In contrast, enzymatic reduction of (-)-sophorol by the pea enzyme sophorol reductase (SOR) produced only the 299.3 nm (-)-DMDI isomer. Proton nuclear magnetic resonance (1H NMR) analysis of the 299.3 nm (-)-DMDI isomer demonstrated that this isomer had the same NMR spectrum as previously reported for cis-isoflavanol isomers, indicating that cis-(-)-DMDI is an intermediate in (+)-pisatin biosynthesis. Enzyme assays using protein extracts from pea tissue treated with CuCl2 as an elicitor converted the cis-(-)-DMDI isomer into an achiral isoflavene, 7,2′-dihydroxy-4′,5′-methylenedioxyisoflav-3-ene (DMDIF), and the trans-(-)-DMDI isomer was not metabolized by the same protein preparation. A comparison of the enzyme activities on cis-(-)-DMDI with protein preparations from elicited tissue versus non-elicited tissue showed a threefold increase in the amount of activity in the proteins from the elicited tissue. Proteins from the elicited tissues of alfalfa, bean, and chickpea converted cis-(-)-DMDI into either (-)-maackiain and/or (-)-sophorol, while proteins from the elicited tissues of broccoli and pepper produced no detectable product. These results are consistent with the involvement of cis-(-)-DMDI and the achiral DMDIF as intermediates in (+)-pisatin biosynthesis.

Studies on the late steps of (+) pisatin biosynthesis: Evidence for (-) enantiomeric intermediates

Pisatin, a 6a-hydroxyl-pterocarpan phytoalexin from pea (Pisum sativum L.), is relatively unique among naturally occurring pterocarpans by virtue of the (+) stereochemistry of its 6a-11a C-C bond. However, pisatin synthesizing pea tissue has an isoflavone reductase, first identified in alfalfa, which acts on the (-) antipode. In order to establish the natural biosynthetic pathway to (+) pisatin, and to evaluate the possible involvement of intermediates with a (-) chirality in its biosynthesis, we administered chiral, tritium-labeled, isoflavanones and pterocarpans to pisatin-synthesizing pea cotyledons and compared the efficiency of their incorporation. Pea incorporated the isoflavanone, (-) sophorol, more efficiently than either its (+) antipode, or the pterocarpans (+) or (-) maackiain. (-) Sophorol was also metabolized by protein extracts from pisatin-synthesizing pea seedlings in a NADPH-dependent manner. Three products were produced. One was the isoflavene (7,2′-dihydroxy-4′,5′-methylenedioxyisoflav-3-ene), and another had properties consistent with the isoflavanol (7,2′-dihydroxy- 4′,5′-methylenedioxyisoflavanol), the expected product for an isoflavanone reductase. A cDNA encoding sophorol reductase was also isolated from a cDNA library made from pisatin-synthesizing pea. The cloned recombinant sophorol reductase preferred (-) sophorol(+) sophorol as a substrate and produced 7,2′-dihydroxy-4′,5′-methylenedioxyisoflavanol. Although no other intermediates in (+) pisatin biosynthesis were identified, the results lend additional support to the involvement of intermediates of (-) chirality in (+) pisatin synthesis.
