Synthesis of four vasopressin analogues which do not contain the glycinamine residue in position 9 and have a basic non-coded amino acid in position 8 is described. All the analogues exhibit very low endocrine activities and are effective in the passive avoidance test.

Valerianaceae, the sub-family of Caprifoliaceae, contains more than 300 species of annual and perennial herbs, worldwide distributed. Several species are used for their biological properties while some are used as food. Species from the genus Valeriana have been used for their antispasmodic, relaxing, and sedative properties, which have been mainly attributed to the presence of valepotriates, borneol derivatives, and isovalerenic acid. Among this genus, the most common and employed species is Valerianaofficinalis. Although valerian has been traditionally used as a mild sedative, research results are still controversial regarding the role of the different active compounds, the herbal preparations, and the dosage used. The present review is designed to summarize and critically describe the current knowledge on the different plant species belonging to Valerianaceae, their phytochemicals, their uses in the treatment of different diseases with particular emphasis on the effects on the central nervous system. The available information on this sub-family was collected from scientific databases up until year 2020. The following electronic databases were used: PubMed, Scopus, Sci Finder, Web of Science, Science Direct, NCBI, and Google Scholar. The search terms used for this review included Valerianaceae, Valeriana, Centranthus, Fedia, Patrinia, Nardostachys, Plectritis, and Valerianella, phytochemical composition, in vivo studies, Central Nervous System, neuroprotective, antidepressant, antinociceptive, anxiolytic, anxiety, preclinical and clinical studies.

Myelin from the central nervous system contains an unusual basic protein, which can induce experimental autoimmune encephalomyelitis. The basic protein from human brain was digested with trypsin and other enzymes and the sequence of the 170 amino acids was determined. The localization of the encephalitogenic determinants was described. Possible roles for the protein in the structure and function of myelin are discussed.

The complete primary structure of the human oligodendrocyte-myelin glycoprotein (OMgp), a glycophospholipid-linked membrane protein of oligodendrocytes and central nervous system myelin, has been determined. The deduced amino acid sequence predicts a polypeptide of 433 amino acids which includes a 17-amino acid leader sequence. OMgp consists of four domains: (a) a short cysteine-rich motif at the NH2 terminus; (b) a series of tandem leucine-rich repeats (LRs) present in several other proteins where they may play roles in adhesion; (c) a serine/threonine-rich region that contains probable attachment sites for O-linked carbohydrates; and (d) a hydrophobic COOH-terminal segment that is likely to be cleaved concomitant with the attachment of lipid during biosynthesis of OMgp. OMgp shares the first three of its four domains with the platelet glycoprotein Ib, which is responsible for the initial adhesion of platelets to the exposed subendothelium during hemostasis. Together with glycoprotein Ib and several other proteins, OMgp belongs to a family of proteins that contain both an NH2-terminal cysteine-rich motif and an adjacent series of LRs. In addition, we report that a subpopulation of OMgp molecules contains the HNK-1 carbohydrate, which has been shown to mediate interactions among cells in the central nervous system.
