Induction of apoptosis is perceived as the main intention of drug regimens for tumour therapy. Thus, the concentration- and time-dependence of drug-induced apoptosis should be carefully evaluated for experimental as well as for standard anti-tumour agents. A main feature of

(S)-Proline-catalyzed nitro-Michael additions of aldehydes and ketones to β-nitrostyrene were investigated computationally (MP2/6-311+G**//M06-2X/6-31G**). Contrary to what is usually assumed in organocatalysis, the lowest-energy transition states of proline-catalyzed nitro-Michael reactions do not necessarily involve the carboxylic acid group of the proline

Protein tyrosine phosphatases (PTPs) catalyze the hydrolysis of phosphotyrosyl (pY) proteins to produce tyrosyl proteins and inorganic phosphate. Specific PTPs inhibitors provide useful tools for studying PTP function in signal transduction processes and potential treatment for human diseases such as

Serendipitous switch: While exploring cis-nitrostyrene as a potential electrophile in Michael-type addition reactions catalysed by the enzyme 4-oxalocrotonate tautomerase (4-OT), it was unexpectedly found that 4-OT catalyses the isomerisation of cis-nitrostyrene to trans-nitrostyrene (k(cat) /K(m) = 1.9×10(3)  M(-1)  s(-1) ).

An efficient asymmetric Michael addition of cyclic ketones to β-nitrostyrenes using secondary diamine as an organocatalyst derived from l-proline and (R)-α-methylbenzyl amine has been described. This pyrrolidine based catalyst 1 was found to be very effective to synthesize various γ-nitrocarbonyl
