Abstract

An insulin analog comprises a B-chain polypeptide containing a cyclohexanylalanine substitution at position B24 and optionally containing additional amino-acid substitutions at positions A8, B28, and/or B29. A proinsulin analog or single-chain insulin analog containing a B domain containing a cyclohexanylalanine substitution at position B24 and optionally containing additional amino-acid substitutions at positions A8, B28, and/or B29. The analog may be an analog of a mammalian insulin, such as human insulin. A nucleic acid encoding such an insulin analog is also provided. A method of lowering the blood sugar of a patient comprises administering a physiologically effective amount of the insulin analog or a physiologically acceptable salt thereof to a patient. A method of semi-synthesis using an unprotected octapeptide by means of modification of an endogenous tryptic site by non-standard amino-acid substitutions.
