摘要:
There are disclosed certain novel compounds identified as benzo-fused lactams which promote the release of growth hormone in humans and animals. This property can be utilized to promote the growth of food animals to render the production of edible meat products more efficient, and in humans, to increase the stature of those afflicted with a lack of a normal secretion of natural growth hormone. Growth promoting compositions containing such benzo-fused lactams as the active ingredient thereof are also disclosed.
摘要:
A series of novel thyrotropin-releasing hormone analogs wherein the C-terminal prolineamide moiety has been preserved, the N-terminal moiety comprises one of five different ring structures and the histidyl moiety is substituted with CF.sub.3, NO.sub.2 or a halogen. A method of use of the analog for the treatment of neurologic disorders is also provided.

摘要:
An N-acylamino acid compound represented by the general formula (1):R--CO--(NH--X--CO).sub.n --OR.sup.1 (1)wherein (NH--X--CO) is an amino acid residue, X in (NX--X--CO) is variable with the kind of amino acid to be used, R--CO is a saturated or an unsaturated fatty acid residue having 6 to 24 carbon atoms, R.sup.1 is hydrogen atom, sodium atom, potassium atom, or methyl group and n is an integer in the range of from 1 to 3, indicating that at least one histidine is contained as a component amino acid is disclosed, which is obtained by causing an N-hydroxysuccinimide ester to react with an amino acid or a peptide.The compound excels in antioxidizing power, emulsifying power, antibacterial power, chelating power, infrared absorbing power, and humidity-retaining power.
摘要:
This invention relates to analogs of peptidase substrates in which the amide group containing the scissile amide bond of the substrate peptide has been replaced by an activated electrophilic ketone moiety. These analogs of the peptidase substrates provide specific enzyme inhibitors for a variety of proteases, the inhibition of which will have useful physiological consequences in a variety of disease states.
