FDA announced on July 16, 2026 that Lipfendra (enlicitide) was approved to be used with diet and exercise to reduce LDL-C in adults with high cholesterol or heterozygous familial hypercholesterolemia. FDA also states that Lipfendra is a tablet taken by mouth once daily and is the first oral therapy that blocks PCSK9.
更多The key correction is that the ACS Organic Process Research & Development paper describes LUNA18 (paluratide) through a liquid-phase peptide synthesis process, not a simple SPPS plus three-fragment route. The paper’s abstract says the authors departed from conventional solid-phase peptide synthesis and developed an LPPS process for an N-alkyl-rich cyclic undecapeptide KRAS inhibitor.

The reported inclisiran architecture illustrates why an siRNA conjugate cannot be reduced to a sequence plus a targeting ligand. Descriptions of that architecture place a triantennary N-acetylgalactosamine (GalNAc) unit at the sense-strand terminus, combine 2'-fluoro and 2'-O-methyl ribose substitutions with terminal phosphorothioate linkages, and rely on the antisense strand for RNA-induced silencing complex (RISC) loading. Each element addresses a different constraint: cell uptake, nuclease exposure, strand handling, or intracellular recognition.
