Angiotensin ii-(3–8)-hexapeptide affects motor activity, performance of passive avoidance and a conditioned avoidance response in rats
Angiotensin II-(3-8)-hexapeptide, at the dose of 1 nmol given intracerebroventricularly, only slightly less than angiotensin II (the same dose and route) stimulated exploratory locomotor behaviour inExpand

A potent new synthetic analog of vasopressin with relative agonist specificity for the pituitary.
The biological activity of a new synthetic analog of vasopressin, deamino[D-3-(3'-pyridyl)-Ala2, Arg8] vasopressin, was assessed in a number of assays. Antidiuretic (V2) and vasoconstrictor (V1),Expand

Separation of siderophores by capillary electrophoresis
Abstract Capillary electrophoresis (CE) was applied as a fast method of siderophore separation. Siderophores are iron binding and regulating cell products, which facilitate iron transport into cells.Expand

Psychotropic effects of angiotensin II and III in rats: Locomotor and exploratory vs cognitive behaviour
One nmol of angiotensin II (AII) or angiotensin III (AIII) given intracerebroventricularly (i.c.v.) increased locomotor and exploratory activity in an open field apparatus but not in theExpand

Design of potent cyclic gonadotropin releasing hormone antagonists.
In order to improve the biological potency of cyclic gonadotropin releasing hormone (GnRH) antagonists, we have synthesized analogues, the conformations of which were restrained through internal sideExpand

Origin of the positive 225-230 nm circular dichroism band in proteins. Its application to conformational analysis.
The 225-230 nm circular dichroism band found in many disulfide-containing proteins and peptides is sensitive to environmental changes. This band is assigned to the disulfide bond, the conformation ofExpand

New analogues of Cucurbita maxima trypsin inhibitor III (CMTI III) with simplified structure.
Seven new analogues of trypsin inhibitor CMTI III were obtained by solid-phase peptide synthesis. Three analogues contained only two, instead of three, disulfide bridges, whereas the molecules of theExpand
