Most common drugs are chemically manufactured, small molecules. Small molecule therapeutics are organic compounds, with a molecular weight of less than ~0.9 kDa, and are typically taken orally. These drugs readily cross cell membranes to reach their drug target and act on physiological processes. An example of a common, small molecule drug is acetylsalicylic acid, the active ingredient of Aspirin, which has a size of 0.18 kDa. In contrast, large molecules, known as biologics or therapeutic proteins, often have to be administered by injection. Insulin, with a molecular weight of 5.8 kDa, is an example of an injected, large molecule drug.
Specifically Manufactured for Quality & Efficacy
Exxel Pharma’s URB597 and URB937 drugs are synthetic, small molecules that are chemically manufactured using specific synthesis steps. The company has patents covering the structure of the therapeutics, their manufacturing process and methods of use.
