The process of drug development involves multiple stages, including drug discovery, preclinical testing, and clinical trials. During the synthesis of a drug, researchers often create several intermediates before arriving at the final product. Each intermediate must be carefully characterized and evaluated for its stability, efficacy, and potential for further reaction. This stepwise approach allows chemists to optimize yields and purity, ultimately refining the synthesis process for the active drug.
While our bodies can produce some PQQ, dietary sources are also critical for maintaining optimal levels. Foods rich in PQQ include fermented soybeans, green peppers, spinach, broccoli, and kiwi. These foods not only supply PQQ but also provide other essential nutrients that contribute to overall health. For individuals seeking to increase their PQQ intake, considering these food sources is a simple yet effective strategy.
