series of 1-[[2-thiazol-5-yl-(2-aminoethyl)]-4-n-propyl]piperazine derivatives have been prepared and in vitro tested as H3-receptor antagonists (the electrically evoked contraction of the guinea pig jejunum). It appeared that by comparison of homologous pairs the 1-[[2-thiazol-5-yl-(2-methyl-2-phenylalkylaminoethyl)]-4-n-propyl]piperazine derivatives (4c1–4c3) have slightly higher activity than their
