    Author: Novelli F, Sparatore F.
    Journal: Farmaco; 1993 Aug; 48(8):1021-49. PubMed ID: 8216667.
    Abstract:
    The (quinolizidin-1 alpha-yl)methanthiol (thiolupinine) was prepared and, utilizing the thiol group reactivity, several S-substituted derivatives were obtained among which was a group of 3-[(lupinylthio)methyl]indoles. Eight of the prepared compounds were subjected to a broad pharmacological screening that evidentiated for many of them good level of the following activities in vivo and in vitro: antiarrhythmic, local anesthetic, negative chronotropic on isolated atria, calcium antagonism on ileum and atria, inhibition of spontaneous contraction of isolated trachea, inhibition of guinea pig ileum contractions induced by angiotensin I and II, bradykinin and cholecystokinin, inhibition of platelet aggregation induced by PAF and ADP. Single compounds were remarkable for additional antagonistic activities: 4 against P1-purine receptor, 8 against substance P, 12 against methacholine and 13 strongly inhibited arachidonate induced platelet aggregation. Very peculiar was the ability of compound 6 to protect mice from PAF induced mortality.
