Selank je syntetick\u00fd heptapeptid zlo\u017een\u00fd zo siedmich aminokysel\u00edn. Bol navrhnut\u00fd ako anal\u00f3g prirodzen\u00e9ho peptidu tufts\u00ednu, ktor\u00fd sa podie\u013ea na komunik\u00e1cii medzi imunitn\u00fdm a nervov\u00fdm syst\u00e9mom.

Afobazol (fabomotizol) je naopak syntetick\u00e1 chemick\u00e1 zl\u00fa\u010denina dostupn\u00e1 vo forme tabliet. Bol vyvinut\u00fd aj v Rusku koncom 90. rokov.

Podobne ako Selank, bol navrhnut\u00fd tak, aby nesp\u00f4soboval v\u00fdrazn\u00fa sed\u00e1ciu.<\/p>\n
