    Abstract: What are described are compounds of formulas II, III, and IV. The compound of formula II consists of a compound in which R1 and R2 are both a linear alkyl consisting of 1 to 12 carbons, an alkenyl or alkynyl consisting of 2 to 12 carbons; L1 and L2 both consist of a linear alkylene or alkenylene consisting of 5 to 18 carbons, or forming a heterocycle with N; X is S; L3 consists of a bond or a linear alkylene consisting of 1 to 6 carbons, or forming a heterocycle with N; R3 consists of a linear or branched alkylene consisting of 1 to 6 carbons; and R4 and R5 are the same or different, each consisting of hydrogen or a linear or branched alkyl consisting of 1 to 6 carbons. The compound of formulas III and IV consists of a compound in which R1 consists of a branched alkyl with 12 to 20 carbons; R2 consists of a linear alkyl with 5 to 10 carbons or a branched alkyl with 12 to 20 carbons; L1 and L2 each consists of a bond or a linear alkyl having 1 to 3 carbon atoms; X consists of S or O; L3 consists of a bond or a lower alkyl; R3 consists of a lower alkyl; and R4 and R5 are the same or different, each consisting of a lower alkyl. The compound of formulas II, III and IV may comprise a pharmaceutically acceptable salt thereof.

    Abstract: A method of producing lipid-encapsulated RNA nanoparticles includes flowing an aqueous solution comprising an RNA through a 1st tube having a first inner diameter (ID); the RNA comprises from about 6,000 to about 13,000 nucleotides; flowing an ethanol solution comprising lipids through a 2nd tube having a second inner diameter (ID), at a flow rate of about 0.2 to about 1 times relative to the aqueous solution through the 1st tube, the lipids comprise a cationic lipid; and mixing the ethanol solution with the aqueous solution; the first ID and second ID and flow rates through the 1st tube and 2nd tube are selected to produce a shear force sufficiently low to preserve the integrity of the RNA; the mixing produces an output solution flowing in the 1st tube comprising a turbulent flow of the RNA and the lipids in between about ethanol, the lipid-encapsulated RNA nanoparticles having a bilayer structure.

    Abstract: A synthetic transfer RNA with an extended anticodon loop. A synthetic suppressor transfer RNA useful for the treatment of a genetic disease like cystic fibrosis associated with a nonsense mutation. The synthetic transfer RNA contains an extended anticodon loop with two consecutive anticodon base triplets configured to base-pair to two consecutive codon base triplets on an mRNA. The first anticodon base triplet or the second anticodon base triplet is configured to base-pair to a stop codon base triplet on the mRNA.
