An object of the present invention is to provide a novel catalyst for olefin (co)polymer production, which has high activity without using a large amount of a cocatalyst and is aimed for obtaining a particulate olefin (co)polymer. The invention relates to an olefin polymerization catalyst which comprises: a solid carrier (1) that has been brought into contact with a specific compound; and a metal catalyst component (2) that contains a transition metal compound (C) containing a transition metal M belonging to Group 9, 10, or 11 of the periodic table and has a reactive group Ra.

kinetic stabilizer, using fibril inhibition potency and plasma TTR bindingselectivity data. Herein, we have successfully employed a substructure combination strategy to use these data to develop potent and selective TTR kinetic stabilizers that rescue cells from the cytotoxic effects of TTR amyloidogenesis. Of the 92 stilbene and dihydrostilbene analogues synthesized, nearly all potently inhibit TTR
