Abstract
Abstract The subject invention relates to compositions and methods for regulating wrinkles in mammalian skin by topical application of a 2-deoxy- or 2-deoxy-2-halo-lysophosphatidic acid compound having the structure: ##STR1## or a pharmaceutically acceptable salt thereof, wherein --R is unsubstituted or substituted, saturated or unsaturated, straight or branched chain alkyl having from 11 to about 23 carbon atoms; each --X-- is independently --0-- or --S--; --Y-- is --0-- or --CH 2 --; and Z is --H or halo.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
104 words
A composition for topical application for preventing, retarding, arresting or reversing the process of wrinkle formation in mammalian skin comprising: (a) a safe and effective amount of a 2-deoxy- or 2-deoxy-2-halo-lysophosphatidic acid compound having the structure: ##STR4## or a pharmaceutically acceptable salt thereof, wherein --R is unsubstituted or substituted, with a substituent selected from the group consisting of halogen, hydroxy, phenyl, amino and acylamino, saturated or unsaturated, straight or branched chain alkyl having from 11 to about 23 carbon atoms; each --X-- independently --O-- or --S--; --Y-- is --O-- or --CH 2 ; and --Z is --H or halo; and (b) a topical carrier.
Claim 2
Dependent Claim
104 words
A composition for topical application for preventing, retarding, arresting or reversing the process of wrinkle formation in mammalian skin comprising: (a) a safe and effective amount of a 2-deoxy- or 2-deoxy-2-halo-lysophosphatidic acid compound having the structure: ##STR4## or a pharmaceutically acceptable salt thereof, wherein --R is unsubstituted or substituted, with a substituent selected from the group consisting of halogen, hydroxy, phenyl, amino and acylamino, saturated or unsaturated, straight or branched chain alkyl having from 11 to about 23 carbon atoms; each --X-- independently --O-- or --S--; --Y-- is --O-- or --CH 2 ; and --Z is --H or halo; and (b) a topical carrier.
Claim 3
Dependent Claim
25 words
The composition of claim 1 wherein the composition comprises from about 0.01% to about 20% of the compound, and the topical carrier comprises an emollient.
Claim 4
Dependent Claim
15 words
The composition of claim 2 wherein --R is unsubstituted or substituted with hydroxy or halogen.
Claim 5
Dependent Claim
14 words
The composition of claim 3 wherein each --X-- is --O--, and --Y-- is --O--.
Claim 6
Dependent Claim
26 words

Claim 8
Dependent Claim
24 words
The composition of claim 6 wherein --Z is --F; and RC(O)O-- is selected from the group consisting of oleyl, palmitoleyl, palmityl, myristyl and lauryl.
Claim 9
Dependent Claim
18 words
The composition of claim 6 wherein the composition comprises from about 0.1% to about 5% of the compound.
Claim 10
Dependent Claim
22 words

Claim 11
Independent Claim
108 words
A method of preventing, retarding, arresting or reversing the process of wrinkle formation in mammalian skin comprising topically applying to the skin of a mammal a composition comprising a safe and effective amount of a 2-deoxy- or 2-deoxy-2-halo-lysophosphatidic acid compound having the structure: ##STR5## or a pharmaceutically acceptable salt thereof, wherein --R is unsubstituted or substituted with a substituent selected from the group consisting of halogen, hydroxy, phenyl, amino and acylamino, saturated or unsaturated, straight or branched chain alkyl having from 11 to about 23 carbon atoms; each 13 X-- is independently --O-- or --S--; --Y-- is --O-- or --CH 2 --; and Z is --H or halo.
Claim 12
Independent Claim
108 words
A method of preventing, retarding, arresting or reversing the process of wrinkle formation in mammalian skin comprising topically applying to the skin of a mammal a composition comprising a safe and effective amount of a 2-deoxy- or 2-deoxy-2-halo-lysophosphatidic acid compound having the structure: ##STR5## or a pharmaceutically acceptable salt thereof, wherein --R is unsubstituted or substituted with a substituent selected from the group consisting of halogen, hydroxy, phenyl, amino and acylamino, saturated or unsaturated, straight or branched chain alkyl having from 11 to about 23 carbon atoms; each 13 X-- is independently --O-- or --S--; --Y-- is --O-- or --CH 2 --; and Z is --H or halo.
