Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
258 words
The method for treating psoriatic lesions in a host in need of such treatment comprising topically applying to said lesions an effective amount of a pharmaceutical preparation comprising a suitable pharmaceutical carrier and a compound selected from the compound of the formulae: ##STR11## wherein R 1 is --OC) n (CH 2 ) m COOR and where n is 0 or 1, m is 1-4, and R is H, --CH 3 or --C 2 H 5 ; or an acid moiety, including an amino acid moiety; R 2 , R 3 and R 4 are, independently, H or R 1 ; and R 5 and R 6 are, independently, H or --CH 3 ; ##STR12## wherein R 1 , R 2 , R 3 and R 4 are, independently, H or --CH 3 ; or R 1 and R 2 and/or R 3 and R 4 taken together are --CH 2 --; R 5 and R 6 are, independently, H or --CH 3 ; and R 7 and R 8 are, independently, H, --SO 3 H or --SO 3 Na; and ##STR13## wherein there are, independently, double or single bonds in the 1-2 and 3-4 positions; and R 1 , R 2 , R 3 and R 4 are, independently, H, --CH 3 , or R 1 and R 2 and/or R 3 and R 4 taken together are --CH 2 --; and R 5 and R 6 are, independently, a 2-12 dienoic fatty acid moiety, a 1-12 mono- or dialkene, --CHO, --COOH or taken together are succinic anhydride.
Claim 2
Independent Claim
258 words
The method for treating psoriatic lesions in a host in need of such treatment comprising topically applying to said lesions an effective amount of a pharmaceutical preparation comprising a suitable pharmaceutical carrier and a compound selected from the compound of the formulae: ##STR11## wherein R 1 is --OC) n (CH 2 ) m COOR and where n is 0 or 1, m is 1-4, and R is H, --CH 3 or --C 2 H 5 ; or an acid moiety, including an amino acid moiety; R 2 , R 3 and R 4 are, independently, H or R 1 ; and R 5 and R 6 are, independently, H or --CH 3 ; ##STR12## wherein R 1 , R 2 , R 3 and R 4 are, independently, H or --CH 3 ; or R 1 and R 2 and/or R 3 and R 4 taken together are --CH 2 --; R 5 and R 6 are, independently, H or --CH 3 ; and R 7 and R 8 are, independently, H, --SO 3 H or --SO 3 Na; and ##STR13## wherein there are, independently, double or single bonds in the 1-2 and 3-4 positions; and R 1 , R 2 , R 3 and R 4 are, independently, H, --CH 3 , or R 1 and R 2 and/or R 3 and R 4 taken together are --CH 2 --; and R 5 and R 6 are, independently, a 2-12 dienoic fatty acid moiety, a 1-12 mono- or dialkene, --CHO, --COOH or taken together are succinic anhydride.
