Question

The average molecular mass of drugs is approximately:

• A. 160-480 g/mol
• B. 1600-4800 g/mol
• C. 10-100 g/mol
• D. 0.1-100 g/mol

Answer 1

Answer: (A)

160-480 g/mol

According to Lipinski's rule of 5, a small molecule drug should have its molecular mass less than 500 daltons i.e., 500 g/mol.
