Icatibant acetate is a synthetic decapeptide approved by the FDA in 2011 for the acute treatment of hereditary angioedema (HAE) in adults. Acting as a potent, selective competitive antagonist of the bradykinin B2 receptor, it counteracts bradykinin‑induced vasodilation and vascular permeability, thereby alleviating swelling, inflammation, and pain during HAE attacks. The peptide incorporates five non‑proteinogenic amino acids, which confer high stability and receptor affinity.

Natural peptides are excellent "molecular keys" - they have high affinity, good selectivity and low toxicity. However, they inherently have three major weaknesses: they are easily chopped up by proteases, have difficulty penetrating cell membranes, and stay in the body for too short a time. Over the past three decades, pharmaceutical professionals have systematically addressed these shortcomings with a "toolbox of special amino acids". This article uses plain language and a large number of charts to guide CMC R&D peers to disassemble and understand this toolbox from principle to implementation.

Pralatrexate is a specialized antifolate chemotherapy drug primarily used for the treatment of relapsed or refractory peripheral T-cell lymphoma (PTCL). Since its introduction, it has become an important therapeutic option for patients who have limited treatment alternatives.

MAAA-1162a (Deruxtecan, MC-GGFG-DXd) is a drug-linker complex of detrastuzumab (DS-8201a), formed by DXd (MAAA-1181a, payload) and maleimide-tetrapeptide linker (MC-GGFG) through chemical coupling.

The synthesis of doxercalciferol (1α-hydroxyvitamin D₂) usually starts with vitamin D₂ (ergocalciferol) as the starting material, and introduces the 1α-hydroxyl group through selective protection, oxidation, and photoisomerization
