Description

Prinomastat is a synthetic hydroxamic acid derivative with potential antineoplastic activity. Prinomastat inhibits matrix metalloproteinases (MMPs) (specifically, MMP-2, 9, 13, and 14), thereby inducing extracellular matrix degradation, and inhibiting angiogenesis, tumor growth and invasion, and metastasis. As a lipophilic agent, prinomastat crosses the blood-brain barrier. Pfizer conducted multicenter, randomized, double-bind, placebo-controlled trials to evaluate the safety and efficacy of prinomastat in combination with standard chemotherapy in patients with advanced hormone refractory prostate cancer and non-small cell lung cancer. However, this study has been terminated for the reason that Prinomastat did not improve the outcome of chemotherapy in non-small cell Lung cancer patients.

Sample Use Guides

In Vivo Use Guide
15 mg twice daily orally continuously, in combination with gemcitabine 1,250 mg/m2 days 1 and 8 plus cisplatin 75 mg/m2 day 1, every 21 days for up to six cycles.
Route of Administration: Oral
In Vitro Use Guide
Prinomastat did not significantly inhibit glioma cell growth at concentrations of 100 nM to 100 uM using BrdUrd staining, [3 H]thymidine labeling, or the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay; significant inhibition of proliferation occurred only at concentrations of 1 mM
