Pronounced analgesic activity of the innovative compound 4-(3,4-dibromthiophencarbonyl)-2,6,8,12-tetraacethyl-2,4,6,8,10,12hexaazatetracyclo[5,5,0,0,0] dodecane (thiowurtzine) was observed in the thermal nociceptive hot plate test and in the acute visceral and somatic deep pain model (acetic acid writhing test). In these experimental models, naloxone-sensitive thiowurtzine-induced analgesia was revealed. The absence of tropism to peripheral opioid receptors in the acetic acid writhing test was demonstrated using naloxone methiodide. Course administration of low-toxic thiowurtzine in effective doses was not associated with ulcerogenic damage to the gastric mucosa in experimental animals.
