Peptides whose aminoacid sequence differs from that of the ACTH-active peptides containing the first three aminoacids of ACTH in that of the serine residues in 1- and 3-position at least that in 3-position is replaced by glycine. These peptides have a stronger and/or longer lasting ACTH-activity than the corresponding peptides containing the natural first three aminoacids.

Certain phthalamic acid compounds are used as latent hardeners for epoxy resin materials. The hardener effect is achieved by curing at elevated temperatures. The compositions are useful as adhesives and in coating applications.

New 2-sulfinyl- or sulfonyl-1,3,4-thiadiazoles, e.g. those of the formula: ##SPC1## And salts thereof are antibacterial agents.

Cyclopropylmethyl chloride or its homologs, which are valuable intermediates or drugs, are prepared by addition of hydrogen bromide to dichloro-n-butenes or their homologs and reaction of the resulting 1-bromo-3,4-dichlorobutanes with metals.

Polymerization products are provided which are obtained by initially preparing a condensate of 1-2 molar equivalents of urea and 1-2 molar equivalents of epichlorohydrin. The polymerization product is then obtained by polymerizing 2-30 percent by weight of the condensate with 98-70 percent by weight of an alkylenimine having one to four carbon atoms such as ethyleneimine. The polymerization products of this invention are especially useful as retention aids for particulate materials, as dye fixat...

A method of distributing the sebaceous secretions of the skin which comprises applying water soluble ester-ether compounds to the skin.

7-(Heterocyclyl-mercaptoacetylamino)-cephalosporanic acids. Use: antibiotics.

Methallyl dichlorides or their homologs are reacted with hydrogen bromide in the presence of a peroxide, to yield 2-bromomethyl-1,3-dichloropropane or its homologs, which are valuable biocides and intermediates.

Compounds of the formula in which R represents an optionally substituted hydrocarbon radical, X represents oxygen or sulphur and Ph a phenylene radical, are useful for the treatment of cardiac insuffiency and as antihypertensive agents.
