Ro 41-0960
Based on 1 Customer Validation
Ro 41-0960 is a CNS-penetrant, orally active catechol-O-methyl transferase (COMT) inhibitor. Ro 41-0960 reduces dopamine catabolism, increases striatal dopamine and DOPAC levels, decreases striatal HVA levels, induces apoptosis, inhibits proliferation and extracellular matrix formation in uterine fibroid cells. Ro 41-0960 arrests or shrinks uterine fibroid lesions in rats. Ro 41-0960 can be used for the research of Parkinson’s disease, uterine leiomyomas, and breast cancer.

Ro 41-0960 (0.05-50 µM; 20 min) directly activates SERCA2a in pig cardiac sarcoplasmic reticulum microsomes with an EC50 of 27 µM and increases ATPase turnover by 38%[3].
Ro 41-0960 (0.5-100 µM; 30 min) exerts concentration-dependent, contrasting marginal effects on Ca2+ transient amplitude and CaTD50, and minimal effects on beat rate, in human iPSC-derived cardiomyocytes[3].
Ro 41-0960 inhibits rat brain COMT with an IC50 of 16 nmol/L and rat liver COMT with an IC50 of 42 nmol/L[4].
Ro 41-0960 (30 min) potently inhibits COMT activity in cytosolic fractions from healthy human mammary tissues, with IC50 values ranging from 5.1 nM to 42.1 nM across 7 individual tissue samples, and fully blocks activity at 0.3 μM[5].
Ro 41-0960 (10 μM; 5-6 h) inhibits COMT activity in MCF-7 human mammary tumor cells by ~98%, reducing catechol estrogen inactivation and increasing catechol estrogen-induced DNA damage by ~200% without causing cytotoxicity[5].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
