Ordering Information

Biological Activity

Temocapril HCl (CS-622) is a long-acting, orally active prodrug that functions as an angiotensin-converting enzyme (ACE) inhibitor. Upon metabolic conversion to its active diacid metabolite temocaprilat, it targets ACE within the renin-angiotensin-aldosterone system (RAAS) to prevent the conversion of angiotensin I to angiotensin II. This inhibition suppresses downstream RAAS signaling, leading to reduced systemic vascular resistance and attenuated blood pressure elevation.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
