T-TYPE CALCIUM CHANNEL BLOCKER

To provide a novel T-type calcium channel blocker. A compound represented by the following General Formula (I), a tautomer or a stereoisomer of the compound, a pharmaceutically acceptable salt of the compound, or a solvate of the compound, the tautomer, the stereoisomer, or the salt is used as a T-type calcium channel blocker. wherein A represents a phenyl which may have a substituent, a 4-membered to 6-membered heteroaryl ring composed of one to three identical or different heteroatoms selected from an oxygen atom, a sulfur atom, and a nitrogen atom and carbon atoms as ring-constituting atoms, or a heterocondensed ring composed of the heteroaryl ring and either a benzene ring or a 6-membered heteroaryl ring composed of one to two nitrogen atoms and carbon atoms, wherein the heteroaryl ring or the heterocondensed ring may have a substituent and is bonded to a nitrogen atom of the adjacent cyclic amino by means of a carbon atom constituting these rings; B represents a phenyl which may have a substituent, a 5-membered or 6-membered heteroaryl ring composed of one to three identical or different heteroatoms selected from an oxygen atom, a sulfur atom, and a nitrogen atom and carbon atoms as ring-constituting atoms, or a heterocondensed ring composed of the heteroaryl ring and either a benzene ring or a 6-membered heteroaryl ring composed of one to two nitrogen atoms and carbon atoms, wherein the heteroaryl ring or the heterocondensed ring may have a substituent and is bonded to the adjacent cyclopropyl ring by means of a carbon atom constituting these rings; R1 and R2, which may be identical or different, each represent a hydrogen atom, a halogen atom, or the like; R3 represents a hydrogen atom, a halogen atom, or the like; n and m, which may be identical or different, each represent 0 or 1; and p represents 1 or 2.

Iron and manganese catalysts for the selective functionalization of arene C(sp2)-H bonds by carbene insertion

The first examples of the direct functionalization of non-activated aryl sp2 C-H bonds with ethyl diazoacetate (N2CHCO2Et) catalyzed by Mn- or Fe-based complexes in a completely selective manner are reported, with no formation of the frequently observed cycloheptatriene derivatives through competing Buchner reaction. The best catalysts are FeII or MnII complexes bearing the tetradentate pytacn ligand (pytacn= 1-(2-pyridylmethyl)-4,7-dimethyl-1,4,7-triazacyclononane). When using alkylbenzenes, the alkylic C(sp3)-H bonds of the substituents remained unmodified, thus the reaction being also selective toward functionalization of sp2 C-H bonds. Exclusive catalysis: Iron- and-manganese-based catalysts selectively functionalize the C(sp2)-H bonds of benzene or alkylbenzenes through the formal insertion of the CHCO2Et group from N2CHCO2Et (see scheme). When using alkylbenzenes, the alkylic C(sp3)-H bonds of the substituents remain unmodified.

Pyridyl amides as potent inhibitors of T-type calcium channels

A novel series of amide T-type calcium channel antagonists were prepared and evaluated using in vitro and in vivo assays. Optimization of the screening hit 3 led to identification of the potent and selective T-type antagonist 37 that displayed in vivo eff
