Compounds of the formula
R1 and R2 are independently alkyl of 1 to 6 carbon atoms, allyl, or substituted allyl of 3 to 6 carbon atoms; R3 is hydrogen, alkyl of 1 to 6 carbon atoms, or cycloalkyl of 3 to 10 carbon atoms; and R4 is phenyl or naphthyl substituted with alkyl of 1 to 6 carbon atoms, alkoxy of 1 to 6 carbon atoms or NR5R6; substituted or unsubstituted phenylalkyl wherein the alkyl group contains 1 to 6 carbon atoms; substituted or unsubstituted 5 to 10 membered heteroaryl having 1 to 3 heteroatoms selected from N, S and O; substituted or unsubstituted cycloalkyl of 3 to 10 carbon atoms; or substituted or unsubstituted cycloalkylalkyl of 4 to 10 carbon atoms; provided that phenyl or naphthyl is substituted with NR5R6 when R1 and R2 is alkyl, are useful in the treatment of various disorders associated bone loss by increased transcription and elevation of plasma calcitonin levels. Such disorders include, but are not limited to: Paget's Disease, post menopausal osteoporosis, senile osteoporosis, and glucocorticoid-induced osteoporosis.
化合物的公式为R1和R2,分别独立地是1到6个碳原子的烷基,烯丙基或3到6个碳原子的取代烯丙基;R3是氢,1到6个碳原子的烷基或3到10个碳原子的环烷基;R4是苯或萘基,取代有1到6个碳原子的烷基,1到6个碳原子的烷氧基或NR5R6;取代或未取代的苯基烷基,其中烷基含有1到6个碳原子;取代或未取代的5到10元杂环芳基,其中有1到3个N、S和O杂原子;取代或未取代的3到10个碳原子的环烷基;或取代或未取代的4到10个碳原子的环烷基烷基;前提是当R1和R2是烷基时,苯或萘基取代有NR5R6。这些化合物在治疗与骨丢失有关的各种疾病中是有用的,通过增加转录和升高血浆降钙素水平。这些疾病包括但不限于:帕吉特病,绝经后骨质疏松症,老年性骨质疏松症和糖皮质激素诱导性骨质疏松症。
