Increasing the ratio of succinate to malonic acid reduces the inhibitory effect of malonic acid. In conclusion, the present study in a small group of patients treated with valproic acid provides a preliminary in vivo evidence that valproic acid is an inhibitor of CYP2C9 activity at steady state. Concerns over the toxicity and side effects of synthetic enzyme inhibitors have led to a search for new safe and effective inhibitors particularly from natural sources. It explored their potential action with respect to lowering maltase, lactase, and sucrase activities in the small intestine of galactomannan-treated diabetic group compared to the diabetic control group. What follows is a very brief and simple look at a very complicated topic. The reaction is inhibited by malonic acid, which resembles succinate but cannot be acted upon by succinate dehydrogenase. Owing to their wide range of biological effects, plant phenolic compounds are one of the most studied families of natural products.
