Nonsteroidal anti-inflammatory drugs and non-narcotic analgesics are widely used to treat various inflammatory diseases of infectious and noninfectious nature [1].The development of new drugs based on terpenophenols, which have a unique set of pharmacological properties [2], is highly promising. The literature teaches that phenols with a bicyclic isobornyl moiety exhibit anti-infection activity [3]. The series of studies performed by us on the synthesis and investigation of terpenophenols showed that some alkylphenols exhibit hemorheological properties and improve brain blood flow [4,5]. Thus, the synthesis of terpenophenols is critical for further studies of their physiological properties.Herein we present results from a study of the anti-inflammatory activity of the synthesized terpenophenols and their aminomethyl derivatives.A series of isobornylphenols (1a-e) with various substituents in the aromatic ring were prepared earlier via alkylation of phenols by the natural monoterpenoid camphene in the presence of the corresponding aluminum phenolates [6][7][8].Continued functionalization of the terpenophenols by introducing aminomethyl moieties using the Mannich reaction synthesized the previously prepared compounds 2a, 2b, and 2d [9] and newly synthesized 2c, the structure of which was confirmed by IR, PMR, and 13 C NMR spectral data.The anti-inflammatory activity of terpenophenols 1-2 was studied using a formalin-induced acute inflammation model in mice [10] (Table 1). Compounds 1a and 2a exhibited reliable anti-inflammatory activity upon parenteral administration. Compound 1a was less active and showed only 10% more inhibition than this control group.
