We compared the effects of Tamerit, Polyoxidony, and Licopid on spontaneous and lipopolysaccharide-stimulated production of interleukin-1 and tumor necrosis factor by mouse peritoneal macrophages in vitro.

In patients with coronary artery disease, undergoing PTCA, the effects of trimetazidine (TMZ), a piperazine-derivative anti-anginal drug, were studied on several indirect markers of systemic inflammatory response: tumor necrosis factor-alpha (TNF-alpha), C-reactive protein (CRP) and NO products (nitrite and nitrate).

Finally, we report the activity of a novel small molecule PAR2 antagonist, N1-3-methylbutyryl-N4-6-aminohexanoyl-piperazine (ENMD-1068), that dose dependently attenuated joint inflammation.

Polyoxidonium (PO) is a high-molecular weight physiologically active compound with pronounced immunomodulating activity, an N-oxidized polyethylene-piperazine derivative.
The analysis of immunomodulating effect produced by PO proved its stimulating activity on some cytokines production in vitro, e.g. interleukin 1beta (IL-1beta), tumor necrosis factor (TNF)-alpha and IL-6.

The presence of the unsubstituted piperazine ring at the C (7)-position was required for both inhibitory activities.

A smaller N-substituent in the piperazine ring was required for inhibition of TNF-alpha production.

Our results showed that m-CPP significantly decreased the production of nitric oxide, tumor necrosis factor-alpha (TNF-alpha), and interleukin-1beta (IL-1beta) in microglia and astrocyte cultures. m-CPP also attenuated the expression of inducible nitric oxide synthase and pro-inflammatory cytokines such as IL-1beta and TNF-alpha at mRNA levels.

Arthritis Rheum. 2007 Mar;56(3):765-71.


Importantly, spontaneous release of tumor necrosis factor alpha and interleukin-1beta from RA synovium was substantially inhibited by ENMD-1068, in a dose-dependent manner.
