The present invention pertains generally to the field of therapeutic compounds, and more specifically to certain oxy phenyl aryl compounds (referred to herein as OPA compounds), as described herein, which, inter alia, inhibit Checkpoint Kinase 2 (CHK2) kinase function. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit CHK2 kinase function, and in the treatment of diseases and conditions that are mediated by CHK2, that are ameliorated by the inhibition of CHK2 kinase function, etc., including proliferative conditions such as cancer, etc., optionally in combination with another agent, for example, (a) a DNA topoisomerase I or II inhibitor; (b) a DNA damaging agent; (c) an antimetabolite or TS inhibitor; (d) a microtubule targeted agent; and (e) ionising radiation.
Compounds of the class of N-[(1-piperidinyl)alkyl]arylcarboxamides, useful as antiemetic and psychotropic agents.

regioselective synthesis of 2,3-disubstituted chromen-4-one derivatives is accomplished from readily available internal alkynes and 2-methoxybenzoyl chlorides. The reaction proceeds via a domino intermolecular Friedel–Crafts acylation/intramolecular vinyl carbocation trapping (or oxa-Michael addition)/demethylation reaction sequence. This Lewis acid promoted method features relatively mild reaction conditions
