BACKGROUND The conversion of nitriles into amides or carboxylic acids by nitrilase has taken its application into consideration, as the scope of its applications has recently been extended. OBJECTIVES In this study, P. aeruginosa RZ44 was isolated from sewage in the Kerman which has Nitrile-degradation activity. In order to improve the nitrilase production, several optimization were done on e...

A new efficient enantioselective conjugate addition strategy has been disclosed to rapidly construct 2-amino-3-nitrile-chromene complexes via a multi-hydrogen-bond cooperative activation model.

Nitrile insertion into a zirconacycloallenoid complex leads to the formation of a seven-membered ring product with an attached boratirane unit.

Nitriles are a diverse group of organic compounds with –C≡N as functional group. Most nitriles are slightly cytotoxic but some cause severe toxic effects. More than 120 naturally occurring nitriles without considering cyanogenic glycosides are present in terrestrial and marine habitats, especially in plant components such as almonds or other fruit pits. The most common group of naturally occurr...

Afatinib (systematic name: N-{4-(3-chloro-4-fluoro-anilino)-7-[(tetra-hydro-furan-3-yl)-oxy]quinazolin-6-yl}-4-(di-methyl-amino)-but-2-enamide), is a specific in-hibitor of the ErbB family of tyrosine kinases. The free base form crystallizes from aceto-nitrile as a mixed water-aceto-nitrile solvent, C24H25ClFN5O3·0.25C2H3N·2H2O. It crystallizes with two independent mol-ecules (A and B) in the a...

Elastomeric materials for sealing devices operated in the Far North, including Republic of Sakha (Yakutia), must be resistant to working environments and have frost wear resistance with acceptable physical mechanical properties. Some listed properties are mutually exclusive not always achievable based on individual rubber. Thus, one promising method elastomeric is use rubber mixtures. In this s...

The title compound [Co(C22H26N4O4)]PF6, commonly known as [Co(bpcd)]PF6, where bpcd(2-) is derived from the historical ligand name N,N'-bis-(2-pyridyl-meth-yl)-trans-1,2-di-amino-cyclo-hexane-N,N'-di-acetate, crystallized by slow evaporation of a saturated aceto-nitrile solution in air. The cation of the hexa-fluorido-phosphate salt has the Co(III) atom in a distorted octa-hedral coordination g...

BACKGROUND The activator P14K is necessary for the activation of nitrile hydratase (NHase). However, it is hard to be expressed heterogeneously. Although an N-terminal strep tagged P14K could be successfully expressed from Pseudomonas putida, various strategies for the over-expression of P14K are needed to facilitate further application of NHase. RESULTS P14K was successfully expressed throug...
