Abstract
Abstract This invention relates to compounds of the formula <IMAGE> I or an optical isomer thereof wherein R1 and R2 are the same or different and are an alkyl or alkenyl group of 6 to 24 carbon atoms; R3, R4 and R5 are the same or different and are alkyl of 1 to 8 carbon atoms, aryl, aralkyl of 7 to 11 carbon atoms, or when two or three of R3, R4, and R5 are taken together to form quinuclidino, piperidino, pyrrolidino, or morpholino; n is 1 to 8; and X is a pharmaceutically acceptable anion.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
A method for the transdermal, topical or ocular delivery of a drug to the skin or to a mucous membrane of a human or animal subject, comprising the steps of: (1) forming a liposome comprising a therapeutically effective amount of a drug and a compound of Formula I: ##STR8## or an optical isomer thereof, wherein R 1 and R 2 are the same or different and are an alkyl or alkenyl group of 6 to 24 carbon atoms; R 3 , R 4 and R 5 are such that: (i) they are the same or different and are each alkyl of 1 to 8 carbon atoms, aryl, or aralkyl of 7 to 11 carbon atoms, or (ii) two taken together form pyrrolidino, piperidino, or morpholino, and the third is alkyl of 1 to 8 carbon atoms, aryl, or aralkyl of 7 to 11 carbon atoms, or (iii) all three together form quinuclidino; n is 1 to 8; and X is a pharmaceutically acceptable anion; and (2) applying the liposome to the skin or a mucous membrane of said subject.
Claim 2
Independent Claim
179 words
A method for the transdermal, topical or ocular delivery of a drug to the skin or to a mucous membrane of a human or animal subject, comprising the steps of: (1) forming a liposome comprising a therapeutically effective amount of a drug and a compound of Formula I: ##STR8## or an optical isomer thereof, wherein R 1 and R 2 are the same or different and are an alkyl or alkenyl group of 6 to 24 carbon atoms; R 3 , R 4 and R 5 are such that: (i) they are the same or different and are each alkyl of 1 to 8 carbon atoms, aryl, or aralkyl of 7 to 11 carbon atoms, or (ii) two taken together form pyrrolidino, piperidino, or morpholino, and the third is alkyl of 1 to 8 carbon atoms, aryl, or aralkyl of 7 to 11 carbon atoms, or (iii) all three together form quinuclidino; n is 1 to 8; and X is a pharmaceutically acceptable anion; and (2) applying the liposome to the skin or a mucous membrane of said subject.
Claim 3
Independent Claim
162 words
A method for the transdermal, topical or ocular delivery of a polyanion, comprising the steps of: (1) forming a polyanion-liposome complex comprising a polyanion and a compound of Formula I ##STR9## or an optical isomer thereof, wherein R 1 and R 2 are the same or different and are an alkyl or alkenyl group of 6 to 24 carbon atoms; R 3 , R 4 and R 5 are such that: (i) they are the same or different and are each alkyl of 1 to 8 carbon atoms, aryl, aralkyl of 7 to 11 carbon atoms, or (ii) two taken together form pyrrolidino, piperidino, or morpholino, and the third is alkyl of 1 to 8 carbon atoms, aryl, or aralkyl of 7 to 11 carbon atoms, or (iii) all three together from quinuclidino; n is 1 to 8; and X is a pharmaceutically acceptable anion; and (2) applying the complex to the skin or mucous membrane of a subject in need thereof.
Claim 4
Independent Claim
162 words
A method for the transdermal, topical or ocular delivery of a polyanion, comprising the steps of: (1) forming a polyanion-liposome complex comprising a polyanion and a compound of Formula I ##STR9## or an optical isomer thereof, wherein R 1 and R 2 are the same or different and are an alkyl or alkenyl group of 6 to 24 carbon atoms; R 3 , R 4 and R 5 are such that: (i) they are the same or different and are each alkyl of 1 to 8 carbon atoms, aryl, aralkyl of 7 to 11 carbon atoms, or (ii) two taken together form pyrrolidino, piperidino, or morpholino, and the third is alkyl of 1 to 8 carbon atoms, aryl, or aralkyl of 7 to 11 carbon atoms, or (iii) all three together from quinuclidino; n is 1 to 8; and X is a pharmaceutically acceptable anion; and (2) applying the complex to the skin or mucous membrane of a subject in need thereof.
