The present invention provides a novel nitrogen-containing heterocyclic compound useful as a phosphodiesterase-4 inhibitor, and a medicament comprising the same. Further, the present invention provides a nitrogen-containing heterocyclic compound represented by the following formula, its salt or hydrates thereof, and a medicament comprising the same.
wherein the ring A is an aromatic hydrocarbon ring which may have a heteroatom, the ring B represents (a) a saturated hydrocarbon ring, (b) an unsaturated hydrocarbon ring, (c) a saturated heterocyclic ring or (d) an unsaturated heterocyclic ring, all of which may have a substituent group.
This invention relates to agents that are inhibitors or activators of variant forms of endogenous proteins and novel methods of identifying such variants. Of particular interest are inhibitors and activators of endogenous protein variants, encoded by genes which have mutated, which variants often arise or are at least first identified as having arisen following exposure to a chemical agent which is known to be an inhibitor or activator of the corresponding unmutated endogenous protein.
Novel hetaryl-[1,8]naphthyridine derivatives of formula (I) wherein R1, R2, W1, W3, W5 and W6 have the meaning according to claim 1, are inhibitors of ATP consuming proteins, and can be employed, inter alia, for the treatment of tumors.

Various 3-aryl-1H-indazol-5-amine derivatives were synthesized by Pd-catalyzed Suzuki–Miyaura cross-couplingreaction of (NH) free 3-bromo-indazol-5-amine with arylboronic acids under microwave-assisted conditions. The coupling reaction can be carried out under the conditions with dioxane/H2O as solvent, Pd(OAc)2 and RuPhos as catalyst system, and K3PO4 as a base in good to excellent yields.
在微波辅助条件下,通过(Pd)催化的(NH)游离3-溴-吲哚-5胺与芳基硼酸的Suzuki-Miyaura交叉偶联反应,合成了各种3-芳基-1 H-吲哚5胺衍生物。可以在以二恶烷/ H 2 O为溶剂,Pd(OAc)2和RuPhos为催化剂体系,以K 3 PO 4为碱的条件下以良好或优异的产率进行偶联反应。
