L(+)-Tartrate strongly inhibits prostatic acid phosphatase (Abul-Fadl and King, 1948, 1949) while having no action on red cell phosphatase. The authors suggested the application of this phenomenon and its diagnostic value as a sensitive test in elucidating doubtful or borderline cases of prostatic cancer. Based on this principle, Fishman and Lerner (1953) described a method for the determinatio...

Chemical mixtures can be leveraged to store large amounts of data in a highly compact form and have the potential for massive scalability owing use large-scale molecular libraries. With parallelism that comes from having many species available, chemical-based memory also provide physical substrate computation with increased throughput. Here, we represent non-binary matrices chemical solutions p...

The objective of this study is to valorize two waste products which, until now, caused major problems concerning their management and impacts on the environment health. This concerns sludge wastewater treatment station city Fez-Morocco olive mill wastewater, which are produced, respectively, in quantities around 51,100 t/year 514,350 m3/year, by pyrolysis for production biochar. obtained biocha...

The photophysical properties and excited-state intramolecular proton transfer (ESIPT) processes for 2-(2′-hydroxyphenyl)-4-chloromethylthiazole (1), 2-(2′-hydroxyphenyl)-4-phenylthiazole (2), 2-(2′-hydroxyphenyl)-4-hydroxymethyl-thiazole (3) were studied at the TD-B3PW91/6–31 + G(d, p)/IEFPCM level. structures of 1–3 fully optimized corresponding structural parameters, infrared spectra electron...

the effect of alkyl substituents on the c-phenyl and/or the n-phenyl ring of benzophenylhydroxamic acid on their molecular structure and hydrogen bonding has been investigated. the predominant configuration in chcl3 is determined by steric and electronic effects. substituents on the c-phenyl ring favor the cis configuration, while substituents in the n-phenyl ring favor a trans configuration. t...

The title compound, C(22)H(18)N(2)O(2), was derived from 1-(2-hydroxy-phen-yl)-3-(4-methoxy-phen-yl)propane-1,3-dione. The central pyrazole ring forms dihedral angles of 16.83 (5), 48.97 (4) and 51.68 (4)°, respectively, with the methoxy-phenyl, phenyl and hydroxy-phenyl rings. The crystal packing is stabilized by O-H⋯N hydrogen bonding.

The title compound, C(20)H(15)BrN(2)O(2), crystallized with three independent molecules in the asymmetric unit. Intramolecular O-H⋯N hydrogen bonds induce coplanarity of the substituted benzene ring and the benzimidazole ring, with mean deviations from the planes of 0.0931 (10), 0.0448 (10) and 0.0083 (11) Å in the three mol-ecules.
