In search for a new lead of non-imidazole histamine H3-receptor antagonists, a series of 1[(2-thiazolopyridine)-4-n-propyl]piperazines, the analogous 1-[(2-oxazolopyridine)-4-npropyl]piperazines, 1-[(2-benzothiazole)-4-n-propyl]piperazine and 1-[(2-benzooxazole)4-n-propyl]piperazine were prepared and in vitro tested as H3-receptor antagonists (the electrically evoked contraction of the guinea-pig jejunum). It appeared

Optically pure enantiomers of the chiral tetrahydroxythiepane derivative 3,6-dihydroxy-4,5-O-isopropylidene-thiepane (3) are obtained using a novel protocol in which a library of all possible stereoisomers of 3 is synthesized, followed by two-step stereoselective chromatography, using, first, conventional achiral and, then, chiral

Volatile fatty acids (VFAs), the intermediate of the anaerobic process, are considered to be the critical, high-sensitive and reliable indicators of the process stability. Close monitoring and control of VFAs are paramount for the efficient operation of the anaerobic reactors.
