Compounds of the general formula ##STR1## wherein n, R.sub.1, R.sub.2 and X are defined herein, are effective inhibitors of polymerization of vinylic monomers, particularly acrylic monomers. The inhibitors are easily, efficiently, and thoroughly removed from solution with the monomer by contact with charcoal.

This invention provides a method of inhibiting aromatase and treating estrogen-dependent diseases in mammals by administering certain azole derivatives. Certain azole derivatives and their pharmaceutical formulations are also provided.

Triazones and triazine thiones are disclosed as corrosion inhibitors for ferrous metals.

This invention relates to methods of preventing or reducing the degradation of elastin and other proteins and thereby preventing or retarding the disease states caused by said degradation by administering compounds, some of which are novel, of the formula: ##STR1## or their pharmacologically acceptable salts.

Aminopeptidase inhibitory activity is exhibited by compounds having the formula ##STR1## wherein R.sub.1 is hydrogen, alkyl, carboxyalkyl, halo-substituted alkyl, hydroxyalkyl, aminoalkyl, mercaptoalkyl, alkylthioalkyl, (cycloalkyl)alkyl, (heteroaryl)alkyl, arylalkyl, carbamoylalkyl, guanidinylalkyl or heteroaryl; and R.sub.2 and R.sub.3 are each independently hydrogen, alkyl, cycloalkyl, hydroxyalkyl, aminoalkyl, aryl, arylalkyl, heteroaryl or heteroarylalkyl.

This invention provides methods of using a number of compounds for the inhibition of lipoxygenase in humans. Pathological conditions which may be treated by the compounds described herein include psoriasis, cellular proliferation, skin allergies, insect bites, allergic rhinitis, conjunctivitis, hay fever, bronchial asthma, allergic gastroenteritis, uterine contractions, hyperactivity of the colon and bronchospasms.

Mercaptoalkanoyl and acylmercaptoalkanoyl compounds of the formula ##STR1## wherein n is an integer from one to fifteen possess enkephalinase inhibition activity and are useful as analgesic agents.

A corrosion inhibitor for mild steel comprising the combination of trimethylolethane or trimethylolpropane with a disclosed alkanolamine.

Renin inhibitory polypeptide analogues derived from the natural N-terminal substrate sequence by replacing the amino acid at position 10 with statine or a residue related to it.

Aminopeptidase inhibitory activity is exhibited by compounds having the formula ##STR1## and pharmaceutically acceptable salts thereof, wherein R.sub.1 and R.sub.2 are each independently hydrogen, alkyl, carboxyalkyl, halo-substituted alkyl, hydroxyalkyl, aminoalkyl, mercaptoalkyl, alkylthioalkyl, (cycloalkyl)alkyl, (heteroaryl)alkyl, arylalkyl, carbamoylalkyl, guanidinylalkyl or heteroaryl; R.sub.3 is hydrogen, alkyl, cycloalkyl, aryl, heteroaryl, arylalkyl, (heteroaryl)alkyl, ##STR2## R.sub.4 ...
