Description: VEL-0230, also known as NC-2300, is a potent cathespin K inhibitor. VEL-0230 has dual-acting properties that both stimulates bone formation and inhibits loss. VEL-0230 is being studied preclinically for the treatment of diseases involving bone mineral disorders such as bone loss related to multiple myeloma, osteoporosis, bone metastases, and rheumatoid arthritis. Velcura Therapeutics is currently being developed by Velcura Therapeutics. Given VEL- 0230's promotion of bone formation, inhibition of bone loss and reduction of calcium levels, Velcura has chosen Myeloma as its lead indication, as the bone fragility, bone pain, high calcium levels and eventual kidney involvement present serious medical and quality of life issues to affected patients.

Preparing Stock Solutions

The following data is based on the product molecular weight 309.33 Batch specific molecular weights may vary from batch to batch due to the degree of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 1.15 mL 5.76 mL 11.51 mL
5 mM 0.23 mL 1.15 mL 2.3 mL
10 mM 0.12 mL 0.58 mL 1.15 mL
50 mM 0.02 mL 0.12 mL 0.23 mL
