A Mannosylated peptidyl lipid CManDA doped into cytidinyl/cationic lipids efficiently delivers siG12Ss to lung cancer in vivo.

Gene therapy has attracted widespread attention in recent years, and one of the important delivery systems is the LNP. However, many LNPs have potential toxicity and accumulate in the liver. Here, we designed and synthesized a Gemini-type mannosylated peptidyl lipid called CManDA(M), which, in combination with the cytidinyl lipid DNCA(D) and the peptidyl lipid CLD(C) (D/50C/50 M), could transfect siRNA (siG12S) into A549 cells to target and silence the KRAS gene.

Innovative insight into the mechanism of enantioselective skin permeation for chiral drugs.

Objectives: A profound comprehension of the molecular mechanisms underpinning the enantioselective transdermal permeation of chiral drugs is critical in the design and assessment of transdermal preparations. The primary objective of this study is to investigate the distinct skin permeation behaviors exhibited by enantiomers of non-steroidal anti-inflammatory drugs (NSAIDs) and elucidate the intricate molecular mechanism at play.

Methods: and transdermal permeation studies of chiral NSAIDs were performed using transdermal patch and solution system.
