Small molecule APIs have long been the backbone of the pharmaceutical industry. They are a class of compounds that typically consist of 20-100 atoms and are easy to define, purify, and study. These compounds have been widely used to treat various diseases and have multiple mechanisms of action, which can be administered orally and across cell membranes to reach intracellular targets. Furthermore, due to physicochemical properties and minute size, they can serve as potent allosteric modulators and enzyme inhibitors targeting intracellular receptors or extracellular proteins in the central nervous system, nucleus, and cytoplasm.

As the world's leading API manufacturer and supplier, Protheragen-ING provides small molecule APIs covering various research fields, including but not limited to the neurological system, cardiovascular and cerebrovascular, anti-tumor, anti-inflammatory, antibiotics, and antiviral. Importantly, our small molecule API products have high purity, good stability, and reliability, and can be widely used in drug development and production fields.
