The present invention provides a method for acylating one or more amino groups of a peptide where the acylation reaction is to be performed in an aqueous mixture containing less than 10% w/w aprotic polar solvent.

Method for producing acylated peptides

Method of acylating peptides and novel acylating agents

A method of selectively acylating an insulin, an insulin analogue or a precursor thereof having a free .epsilon.-amino group of a Lys residue contained therein and at least one free .alpha.-amino group which method comprises reacting the .epsilon.-amino group with an activated amide in a polar solvent in the presence of a base.

Selective acylation method

The invention provides a series of crystalline salts of (S)-8-chloro-5-(5-bromo-2,3-dihydrobenzofuran-7-yl)-3-methyl-2,3,4,5-tetra hydro-1H-3-benzazepine-7-ol, their preparation and use as therapeutic agents.

Acid addition salts of 2, 3, 4, 5-tetrahydro-1H-3-benzazepine compounds

Indole derivatives of formula (I) ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 may be hydrogen or lower alkyl optionally substituted by halogen; A.sup.1 represents a straight or branched alkylene chain containing from 2 to 4 carbon atoms; R.sup.5 is hydrogen or a straight or branched alkyl group; A.sup.2 is a straight or branched, saturated or unsaturated hydrocarbon chain containing from 2 to 6 carbon atoms; and R.sup.6 is selected from a group consisting of various structures, have been found to exhibit central nervous system activities.

Indole derivatives and their use

Indole derivatives of formula (I) ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 may be hydrogen or lower alkyl optionally substituted by halogen; X represents oxygen or sulfur; A.sup.1 represents a straight or branched alkylene chain containing from 2 to 4 carbon atoms; R.sup.5 is hydrogen or a straight or branched alkyl group; A.sup.2 is a straight or branched, saturated or unsaturated hydrocarbon chain containing from 2 to 6 carbon atoms; and R.sup.6 is selected from a group consisting of various structures, have been found to exhibit central nervous system activities.

Aza spiro decane and use thereof in treating CNS disorders

Novel 2, 3, 4, 5-tetrahydro-1H-3-benzazepines, which in the 7-position have a methoxymethyloxy group, in the 8-position hydrogen, halogen, or a nitro group and in the 5-position have an optionally substituted phenyl ortho-fused ring-system, with interesting effects on the central nervous system.

Benzazepines

Novel 2,3,4,5-tetrahydro-1H-3-benzazepines having the formula ##STR1## wherein R.sup.3 represents H, C.sub.1-3 -alkyl or C.sub.3-7 -cycloalkyl;

Novel benzazepine derivatives
