For a series of beta-homophenylalanine based inhibitors of dipeptidyl peptidase IV ADME properties were improved by the incorporation of amide replacements. These efforts led to a novel series of potent and selective inhibitors of DPP-4 that exhibit an attractive pharmacokinetic

The effect of five topolins (meta-Topolin=mT; meta-Topolin riboside=mTR; meta-Methoxy topolin=MemT; meta-Methoxy topolin riboside=MemTR and 6-(meta-methoxy)-9-(tetrahydropyran-2-yl)-topolin=MemTTHP) on the photosynthetic pigments and leaf structures of micropropagated 'Williams' bananas was compared with the commonly used benzyladenine (BA). Surface-decontaminated explants were cultured for 70

A dihydropyrimidinase gene (pydB) was cloned from the moderate thermophilic Brevibacillus agri NCHU1002 and expressed in Escherichia coli. The purified dihydropyrimidinase exhibited strict d-enantioselectivity for D,L-p-hydroxyphenylhydantoin and D,L-5-[2-(methylthio)ethyl]hydantoin, and non-enantiospecificity for D,L-homophenylalanylhydantoin (D,L-HPAH). The hydrolytic activity of PydB was enhanced
Over the past decade, L-homophenylalanine is extensively used in the pharmaceutical industry as a precursor for production of angiotensin-converting enzyme (ACE) inhibitor, which possesses significant clinical application in the management of hypertension and congestive heart failure (CHF). A number of

Calcium-dependent protein kinases (CPKs) play important roles in multiple signal transduction pathways but the precise role of individual CPK is largely unknown. We isolated two cDNAs encoding two CPK isoforms (Cicer arietinum CPKs-CaCPK1 and CaCPK2) of chickpea. Their expression in
