摘要:
The present invention provides a pharmaceutical composition which is useful as a phosphatidylinositol 3 kinase (PI3K) inhibitor and an antitumor agent, and it provides a novel bicyclic or tricyclic fused heteroaryl derivative or a salt thereof which possesses an excellent PI3K inhibiting activity and cancer cell growth inhibiting activity.
摘要:
The present invention relates to thiazole derivative represented by the general formula (I): ##STR1## or a pharmaceutically acceptable salt thereof, which has a selective agonistic activity for 5-HT.sub.3 receptor, a pharmaceutical composition thereof, and a process for producing the same.
摘要:
The present invention relates to novel compounds having a phosphatidylinositol 3 kinase (PI3K) inhibiting activity which are useful as medicaments, more particularly as antitumor agent. Novel 3-(imidazo[1,2-a]pyridin-3-yl) derivatives or salts thereof exhibit an excellent PI3K inhibiting activity and cancer cell growth inhibiting activity, and are thus useful as medicaments, especially as PI3K inhibitors and antitumor agents.
摘要:
A benzodiazepine derivative of formula I, or a pharmaceutically acceptable salt thereof: ##STR1## wherein: (a) R.sup.4 is an alkyl, cycloalkyl or aryl group. (b) R.sup.10 is chosen from halo, OH, CH.sub.3, OCH.sub.3, NR.sup.11 R.sup.12, NO.sub.2, NHCHO, CO.sub.2 H and CN, and R.sup.11 and R.sup.12 are independently selected from H and alkyl (C.sub.1 -C.sub.5) or together NR.sup.11 R.sup.12 form a cyclic structure II, ##STR2## wherein a is 1-6; and (c) R.sup.2 is an aromatic 5- or 6-membered, substituted or unsubstituted heterocycle containing at least two heteroatoms of which at least one is nitrogen. These compounds are gastrin and/or CCK-B receptor antagonists.
摘要:
A process is provided for preparing a tetrahydrobenzimidazole derivative represented by Formula (Ib): ##STR1## wherein Het representa s heterocyclic group which may be substituted with 1 to 3 substituents selected from the group consisting of a lower alkyl group, a lower alkenyl group, a lower alkynyl group, a cycloalkyl-lower alkyl group, an aralkyl group, a lower alkoxycarbonyl group, and a halogen atom; and X.sup.2 represents a single bond connected to the carbon atom of the heterocyclic ring as represented by Het. The process comprises reacting a heterocyclic compound represented by Formula (IIIa):Het--X.sup.2 --H (IIIa)wherein Het and X.sup.2 are as defined above, with a carboxylic acid represented by Formula (II): ##STR2## or a reactive derivative thereof.
