PSP-94: use for treatment of hypercalcemia and bone metastasis

摘要

The present invention discloses the use of PSP-94, PCK3145 and other derivatives and biologically active analogues for treating a patient having a condition such as metastasis, metastatic cancer, a condition associated with elevated levels of parathyroid hormone-related protein (PTHrP), PTHrP-induced osteolysis and/or hypercalcemia of malignancy. These compounds were found to be effective treatment modalities for bone metastasis caused by prostate cancer. Furthermore, decrease in cellular and plasma PTHrP levels as well as plasma calcium levels observed by treatment with such compound can serve as useful biochemical markers for monitoring the efficacy of these anti-metastatic compounds.
