2,4-DIAMINO-6,7-DIHYDRO-5H-PYRROLO[2,3]PYRIMIDINE DERIVATIVES AS FAK/Pyk2 INHIBITORS

The invention relates to a novel class of 2,4-diamino-6,7-dihydro-5H-pyrrolo[2,3]pyrimidine derivatives as a FAK and/or Pyk2 inhibitor, to a process for their preparation, and to a composition thereof, as well as to use of the compounds for the inhibiting FAK and/or Pyk2 and method for the treatment of a FAK and/ or Pyk2 mediated disorder or disease.

THIAZOLE DERIVATIVES AS PROTEIN KINASE INHIBITORS

The present invention relates to novel Thiazole Derivatives, compositions comprising the Thiazole Derivatives, and methods for using the Thiazole Derivatives for treating or preventing a proliferative disorder, an anti-proliferative disorder, inflammation, arthritis, a central nervous system disorder, a cardiovascular disease, alopecia, a neuronal disease, an ischemic injury, a viral infection, a fungal infection, or a disorder related to the activity of a protein kinase.

N-((phenyl, benzodioxinyl or N-heteroarylpiperazinyl)alkyl)-N-(N-heteroaryl)substituted carboxamides

Piperazine derivatives of formula I and their pharmaceutically acceptable acid addition salts are 5-HT1A binding agents, particularly 5-HT1A antagonists and may be used, for example, as anxiolytics. In the formula A is C2-4 alkylene chain optionally substituted by lower alkyl, Z is oxygen or sulphur, R is hydrogen or lower alkyl, R1 is a mono or bicyclic aryl or heteroaryl radical, R2 is a mono or bicyclic heteroaryl radical and R3 is hydrogen or a specified radical such as lower alkyl, cycloalkyl, aryl, heteroaryl or optionally substituted amino.

PIPERAZINE DERIVATIVES AS 5-HT ANTAGONISTS

This invention concerns compounds of formula (I) STR1 where A is a C 1 or C 2 alkylene chain optionally substituted by lower alkyl; Z is a bicyclic oxygen-containing aryl radical (e.g. 2,3-dihydro-1,4-benzodioxin-5-yl); R is hydrogen or lower alkyl; R 1 is aryl or aryl(lower)alkyl; R 2 is hydrogen or lower alkyl; and R 3 is hydrogen, an alkyl group of 1 to 10 carbon atoms, cycloalkyl of 3 to 12 carbon atoms; cycloalkyl(lower)alkyl, aryl or aryl(lower)alkyl or R. sup.2 and R 3 together with the nitrogen atom to which they are both attached represent a saturated heterocyclic ring which may contain a further hetero atom, and the pharmaceutically acceptable acid addition salts thereof. The compounds are 5-HT 1A-antagonists which may be used, for example, in treating anxiety.

Influence of the Heterocyclic Side Ring on Orientation During Nitrations of 1,2-Alkylenedioxy-annelated Benzenes and Their Mononitro Derivatives

Nitration of 1,2-alkylenedioxybenzenes 1 furnished the respective nitro derivatives 3 and 4 in the relative ratios: 4a:3a/100:trace, 4b:3b/98:2.4, 4c:3c/86:14, 4e:3e/91:9, 4f:3f/99:1.3.Nitration of 4 gave 5a:6a:8a/0:0:100, 5b:6b:8b/7.7:3.2:89, 5c:6c:8c/23:12:65, 5d:6d:8d/14:74:12, 5e:6e:8e/27:18:55 and 5f:6f:8f/23:7.0:70.Nitration of the isomeric 3 afforded the dinitroproducts 5, 6 and 7 in the following relative ratios: 5a:6a:7a/92:8:0, 5b:6b:7b/80:20:0, 5c:6c:7c/69:20:11, 5d:6d:7d/45:19:36, 5e:6e:7e/37:57:5.9 and 5f:6f:7f/64:36:0.Nitration of 3-nitro-1,2-dimethoxybenzene (9) furnished: 10:11/63:37.Orientation as a function of the h eterocyclic ring-size is discussed.
