integrin receptor, the novel compounds themselves, their use, and pharmaceutical preparations comprising these compounds.
Solid-phase synthesis and SAR of alpha(V)beta(3)-receptor antagonists based on a NI-substituted 4-amino-1H-pyrimidin-2-one scaffold are described. The most potent compounds exhibited IC50 values towards alpha(V)beta(3) in the nano- to subnanomolar range and high selectivity versus related integrins like alpha(IIb)beta(3). For selected examples efficacy in functional cellular assays was demonstrated. (C) 2002 Published by Elsevier Science Ltd.

A liquid crystal alignment agent allowing formation of an LCD element having good reliability and less residual image, a liquid crystal alignment film, and an LCD element having the liquid crystal alignment film are shown. The liquid crystal alignment agent includes a polymer (A), a photosensitive polysiloxane (B), and a solvent (C). The polymer (A) is obtained by reacting a mixture that includes a tetracarboxylic dianhydride component (a-1) and a diamine component (a-2). The photosensitive polysiloxane (B) is obtained by reacting a polysiloxane (b-1) having an epoxy group with a cinnamic acid derivative (b-2) and an aromatic heterocyclic derivative (b-3) containing nitride, oxide or sulfide.
