Abstract
Retinoid-like activity is exhibited by compounds of the formula ##STR1## where X is S, O, or NR' where R' is hydrogen or lower alkyl; R is hydrogen or lower alkyl; A is pyridyl, thienyl, furyl, pyridazinyl, pyrimidinyl or pyrazinyl; n is 0-4; and B is H, --COOH or a pharmaceutically acceptable salt, ester or amide thereof, --CH.sub.2 OH or an ether or ester derivative, or --CHO or an acetal derivative, or --COR.sub.1 or a ketal derivative where R.sub.1 is --(CH.sub.2).sub.m CH.sub.3 where m is 0-4, or a pharmaceutically acceptable salt thereof.
Claims21
A process of treating a mammal afflicted with a condition or disease which is susceptible to treatment by a therapeutic agent having retinoid-like activity, the process comprising administering to said mammal an effective dose of a pharmaceutical composition including a pharmaceutically acceptable excipient and a compound having the formula ##STR11## where X is S, O, or NR' where R' is hydrogen or lower alkyl;
- R is hydrogen or lower alkyl;
- A is pyridyl, thienyl, furyl, pyridazinyl, pyrimidinyl or pyrazinyl;
- n is 0-4;
- and B is H, --COOH or a pharmaceutically acceptable salt thereof, or an ester thereof with a saturated aliphatic alcohol of ten or fewer carbon atoms, or with a cyclic or saturated aliphatic cyclic alcohol of 5 to 10 carbon atoms, or with phenol or with a lower alkylphenol, or an amide or a mono or di-substituted amide thereof, the subtituents on the amide being selected from a group consisting of saturated aliphatic radicals of ten or fewer carbon atoms, cyclic or saturated aliphatic cyclic radicals of 5 to 10 carbon atoms, and phenyl or lower alkylphenyl radicals, or B is CH.sub.2 OH or an ester derivative thereof derived from a saturated aliphatic acid of ten or fewer carbon atoms, or from a cyclic or saturated aliphatic cyclic acid of 5 to 10 carbon atoms, or from benzoic acid, or an ether derivative thereof derived from a saturated aliphatic radical of ten or fewer carbon atoms, or from a cyclic or saturated aliphatic cyclic radical of 5 to 10 carbon atoms, or from phenyl or lower alkylphenyl radical, or B is --CHO or a lower alkyl acetal derivative thereof, or an acetal derivative thereof formed with a lower alkyl diol, or B is --COR.sub.1 or a lower alkyl ketal derivative thereof, or a ketal derivative thereof formed with a lower alkyl diol, where R.sub.1 is --(CH.sub.2).sub.m CH.sub.3 where m is 0-4, or a pharmaceutically acceptable salt of the compound defined in said formula.
A process of treating a mammal afflicted with a condition or disease selected from actinic keratoses, arsenic keratoses, inflammatory acne, non-inflammatory acne, psoriasis, ichthyoses, keratinization, hyperproliferative disorders of the skin, eczema, atopic dermatitis, Darriers disease, lichen planus, glucocorticoid damage (steroid atrophy), topical microbial infection, skin pigmentation, photo damage to the skin, premalignant and malignant hyperproliferative diseases, cancers of the breast, skin, prostate, cervix, uterus, colon, bladder, esophagus, stomach, lung, larynxy, oral cavity, blood and lymphatic system, metaplasias, dysplasias, neoplasias, leukoplakias, papillomas of the mucous membranes, Kaposi's sarcoma, proliferative vitreoretinopathy (PVR), retinal detachment, dry eye and other corneopathies, dyslipidemias, post-angioplasty restenosis, diseases associated with Human papilloma virus (HPV), inflammatory diseases, pulmonary fibrosis, ileitis, colitis, Krohn's disease, neurodegenerative diseases, Parkinson's disease and stroke, improper pituitary function, modulation of apoptosis, diseases of the immune system, modulation of organ transplant rejection and facilitation of wound healing, and as agent to increase the level of circulating tissue plasminogen activator (TPA) and for restoring hair growth,
- the process comprising administering to said mammal an effective dose of a pharmaceutical composition including a pharmaceutically acceptable excipient and a compound having the formula ##STR12## where X is S, O, or NR' where R' is hydrogen or lower alkyl;
- R is hydrogen or lower alkyl;
- A is pyridyl, thienyl, furyl, pyridazinyl, pyrimidinyl or pyrazinyl;
- n is 0-4 and B is H, --COOH or a pharmaceutically acceptable salt thereof, or an ester thereof with a saturated aliphatic alcohol of ten or fewer carbon atoms, or with a cyclic or saturated aliphatic cyclic alcohol of 5 to 10 carbon atoms, or with phenol or with a lower alkylphenol, or an amide or a mono or di-substituted amide thereof, the subtituents on the amide being selected from a group consisting of saturated aliphatic radicals of ten or fewer carbon atoms, cyclic or saturated aliphatic cyclic radicals of 5 to 10 carbon atoms, and phenyl or lower alkylphenyl radicals, or B is CH.sub.2 OH or an ester derivative thereof derived from a saturated aliphatic acid of ten or fewer carbon atoms, or from a cyclic or saturated aliphatic cyclic acid of 5 to 10 carbon atoms, or from benzoic acid, or an ether derivative thereof derived from a saturated aliphatic radical of ten or fewer carbon atoms, or from a cyclic or saturated aliphatic cyclic radical of 5 to 10 carbon atoms, or from phenyl or lower alkylphenyl radical, or B is --CHO or a lower alkyl acetal derivative thereof, or an acetal derivative thereof formed with a lower alkyl diol, or B is --COR.sub.1 or a lower alkyl ketal derivative thereof, or a ketal derivative thereof formed with a lower alkyl diol, where R.sub.1 is --(CH.sub.2).sub.m CH.sub.3 where m is 0-4, or a pharmaceutically acceptable salt of the compound defined in said formula.
