摘要:
Methods for treating and preventing multiple sclerosis by administering to a patient an effective amount of calcitonin, calcitonin-like peptides or calcitonin mimetics to a patient. Additionally, 1,25-dihydroxyvitamin D analogs can be used in combination with the calcitonin, calcitonin-like peptides or calcitonin mimetics.
摘要:
This invention discloses 2α-methyl-19-nor-vitamin D analogs, and specifically 2α-methyl-19-nor-1α-hydroxy-homopregnacalciferol and pharmaceutical uses therefor. This compound exhibits pronounced activity in arresting the proliferation of undifferentiated cells and inducing their differentiation to the monocyte thus evidencing use as an anti-cancer agent and for the treatment of skin diseases such as psoriasis as well as skin conditions such as wrinkles, slack skin, dry skin and insufficient sebum secretion. This compound also has little, if any, calcemic activity and therefore may be used to treat autoimmune disorders or inflammatory diseases in humans as well as renal osteodystrophy. This compound may also be used for the treatment or prevention of obesity.
摘要:
A porphyrin ring-fusion polymer which consists of two or more ZnII-porphyrin rings fused in a single direction and in which any two porphyrin rings adjacent to each other are fused by three covalent bonds, that is, one meso-meso carbon bond (i.e., one bond between meso-position carbon atoms) and two β-β carbon bonds (i.e., two bonds between β-position carbon atoms adjacent to the meso-position carbon atoms); a process for preparing the porphyrin ring-fusion polymer regioselectively by conducting the fusion reaction in an aromatic hydrocarbon solvent in the presence of a quinone and a Lewis acid containing a rare earth element under reflux; and fused-ring porphyrin compounds obtained by subjecting the prophyrin ring-fusion polymer to demetallization or replacement of the Zn atoms by other metal atoms.
摘要:
A photocatalyst which comprises an oxysulfide containing at least one transition metal; a preferable photocatalyst which also comprises a rare earth element such as Sm in addition to the above and wherein the transition metal is at least one selected from the group consisting of Ti and Nb; a more preferable photocatalyst which further comprises an auxiliary catalyst comprising a transition metal such as Pt carried on each of the above photocatalysts; and a catalyst for use in the decomposition of water by a light which comprises one of the above oxysulfide photocatalysts.
