A pyrazolopyrimidine derivative represented by formula (1) and pharmaceutically acceptable salt thereof exhibit excellent inhibitory activity against MAPKAP-K2. Accordingly, medicines containing this compound as an active ingredient are expected to be effective for treating diseases mediated by MAPKAP-K2 such as, for example, inflammatory disorder, autoimmune diseases, destructive osteopathy, cancer and/or tumor growth.
Pharmaceutical compositions for inhibiting the aggregation of erthyrocytes or thrombocytes which include phenylamides which conform to the formula: ##STR1## with R.sub.1-6, X, A and B being as defined. Processes for the preparation of novel phenylamides coming within the above formula are also discussed.

of KOBut involves C–H/N–H oxidative annulation to give 1(2H)-isoquinolinones. A key to the success of the reaction is the use of a catalytic amount of strong base, such as KOBut. The reaction shows a high functional group compatibility. The reaction with unsymmetrical alkynes, such as 1-arylalkynes, gives the corresponding 1(2H)-isoquinolinones with a high level of regioselectivity. This discovery would

A metal-free approach was developed for the mild synthesis of N-aryl alpha-alkynyl imines from corresponding amide precursors for the first time. The electronic effects of substrates and the reaction mechanisms were investigated and discussed. This newly developed oxophosphonium-triggered one-pot multiple-step method presents the advantages of mild conditions, ease of operation and satisfactory efficiency. (c) 2008 Elsevier Ltd.
