The application relates to lipids of Formula (A-1) and compositions involving the same. Lipid nanoparticles (e.g., empty LNPs or loaded LNPs) include such a lipid as well as additional lipids such as phospholipids, structural lipids, and PEG lipids. Lipid nanoparticles (e.g., empty LNPs or loaded LNPs) further including therapeutic and/ or prophylactics such as RNA are useful in the delivery of therapeutic and/or prophylactics to mammalian cells or organs to, for example, regulate polypeptide, protein, or gene expression.
Synthesis of substituted uracils by the reactions of halouracils with selenium, sulfur, oxygen and nitrogen nucleophiles under focused microwave irradiation
Undermicrowaveirradiation, the nucleophilic substitutionreactions of halouracils with selenium, sulfur, oxygen and nitrogen nucleophiles was complete within several minutes with yields up to 99%. The method using microwaveirradiation is superior to those conducted under conventional heating processes.
