• Synthesis of new (R)-secondary carbinols with different structures via enzymatic resolution

  The present study deals with the biocatalytic enantioselective synthesis of 19 new chiral alcohols with alkyl (C-11-C-19) and phenyl, substituted phenyl, heteroaromatic, and naphthyl groups 4a-4z with an (R)-configuration and high enantiomeric excess (similar to 100%). The corresponding ketones 1a-1z were synthesized and then reduced with NaBH4 to their racemic alcohols 2a-2z, which were converted into their racemic acetyl derivatives 3a-3z. Enzymes of four different types were used for the enantioselective hydrolysis of these acetyl compounds 3a-3z. The optimal reaction conditions for these four enzymes were established by investigating the enantiomeric excesses by chiral HPLC. Amano lipase from Burkholderica cepacia (Pseudomonas cepacia) AL-PS was determined as the best enzyme in this work This study presents an environmentally friendly and green chemistry method for the synthesis of these new (R)-chiral carbinols 4a-4z.

  The roles of the endothelium‐derived nitric oxide, prostacyclin and endothelium‐derived hyperpolarizing factor (EDHF) in mediating vasodilator responses to acetylcholine and bradykinin were assessed in the ciliary vascular bed of the bovine isolated perfused eye preparation. Vasodilatation to acetylcholine or bradykinin was unaffected by the nitric oxide synthase inhibitor, L‐NAME (100 μM), or the cyclo‐oxygenase inhibitor, flurbiprofen (30 μM), but was virtually abolished following treatment with a high concentration of KCl (30 mM), or by damaging the endothelium with the detergent, CHAPS (0.3%, 2 min). Acetylcholine‐induced vasodilatation was unaffected by glibenclamide (10 μM), an inhibitor of ATP‐sensitive K+ channels (K+ATP), but was significantly attenuated by TEA (10 mM), a non‐selective inhibitor of K+ channels. The small conductance calcium‐sensitive K+ channel (SK+Ca) inhibitor, apamin (100 nM), and the large conductance calcium‐sensitive K+ channel (BK+Ca) inhibitor, iberiotoxin (50 nM), had no significant effect on acetylcholine‐induced vasodilatation. In contrast, the intermediate (IK+Ca)/large conductance calcium‐sensitive K+ channel inhibitor, charybdotoxin (50 nM), powerfully blocked these vasodilator responses, and uncovered a vasoconstrictor response. The combination of apamin (100 nM) with a sub‐threshold concentration of charybdotoxin (10 nM) significantly attenuated acetylcholine‐induced vasodilatation, but the combination of apamin (100 nM) with iberiotoxin (50 nM) had no effect. In conclusion, blockade by a high concentration of KCl, by charybdotoxin, or by the combination of apamin with a sub‐threshold concentration of charybdotoxin, strongly suggests that vasodilatation in the bovine isolated perfused eye is mediated by an EDHF.
