Novel compounds which are amide derivatives represented by general formula (I) and medicinal preparations containing the same having an eosinophilic infiltration inhibitory effect based on a potent interferon (α,γ)-inducing activity and an exellent percutaneous absorbability and being efficacious in treating allergic inflammatory diseases such as atopic dermatitis, various tumors and viral diseases. In said formula, each symbol has the following meaning: R1 and R2 : each lower alkyl, etc.; X and Y: independently representing each oxygen, NR4, CR5 etc. (wherein R4 and R5 independently represent each hydrogen, an aromatic group, etc.); Z: an aromatic ring or heterocycle; R3 : hydrogen, lower alkoxy, etc.; g, i and k: independently representing each an integer of from 0 to 6; h, i and l: independently representing each an integer of 0 or 1; m: an integer of from 0 to 5; and n: an integer of from 2 to 12.

In an effort to prepare nonsteroidal antiestrogens demonstrating greater antagonism and less intrinsic estrogenicity than those currently available, a series of 3-aroyl-2-arylbenzothiophene derivatives was synthesized.These compounds were prepared by Friedel-Crafts aroylation of appropriate O-protected 2-arylbenzothiophene nuclei with basic side-chain-bearing benzoyl chlorides followed by removal of the protective groups to provide the desired compounds containing both hydroxyl and basic side-chain functionality.A particularly useful method for the cleavage of aryl methoxy ethers without removal of (dialkylamino)ethoxy side chain functionality elsewhere in the molecule was found to be AlCl3/EtSH.The benzothiophene derivatives were tested for their ability to inhibit the growth-stimulating action of estradiol on the immature rat uterus.Seemingly minor changes in the side-chain amine moiety were found to have profound effects on the ability of the compounds to antagonize estradiol.Analogues having basic side chains containing cyclic (pyrrolidine, piperidine, and hexamethyleneamine) moieties were found to have less intrinsic estrogenicity and to antagonize estradiol action more completely than their noncyclic counterparts.The most effective antiestrogen in the series, compound 44, thien-3-yl>phenyl>methanone, elicited a modest uterotropic activity that did not increase with increasing dose.In antagonism of estradiol, 44 exhibited a degree of inhibition surpassing that of tamoxifen at any dose tested.The new benzothiophene antiestrogen was also shown to have high affinity for rat uterine cycloplasmic estrogen receptor and to be an inhibitor of the growth of DMBA-induced rat mammary tumors.
