The synthesis and spectroscopic characterization of the rhodium(I) complex 1 incorporating a substituted thienopyrimidine ligand (tpc) was reported. The solid‐state structures of tpc and 1 were determined, for the first time, by single‐crystal X‐ray diffraction. The biological evaluation of the new compounds (tpc and 1) towards the PAF‐induced aggregation in both WRPs and human platelets (hPRPs) showed that complex 1 proved to be a very potent antiplatelet and antithrombotic agent, showing better efficiency than that of the free ligand.
Antiplatelet therapies are discussed with a view to primary prevention of CVD by the clinical reduction of platelet reactivity and inflammation. Current antiplatelet therapies are effective in reducing cardiovascular risk but increase bleeding risk. Novel therapeutic antiplatelet approaches beyond current pharmacological modalities that do not increase the risk of bleeding require further investigation. There is potential for specifically designed nutraceuticals that may become safer alternatives to pharmacological antiplatelet agents for the primary prevention of CVD but there is serious concern over their efficacy and regulation, which requires considerably more research.
The intra- and inter-relationships of Covid-19, inflammation, nutrition, the Mediterranean Diet and thrombosis.
Platelet aggregation as caused by covid-19 related inflammation and the protective role of diet against thrombosis and covid-19.
Turning people to vegans, there is a loss: their diet suffers from lack of essential amino acids and lipid-soluble vitamins (A, D, E and K).
This is the reason that we need to stop the nonsense of “light” (reduced fat) foods and focus to the high nutritional value of full fat meat, dairy, fish. The animal fats (lipids) are healthy. Nations who eat red meat and full fat foods have lower levels of obesity and CVD (CardioVascular Diseases) and other NCD (Non-Communicable Diseases) to nations (e.g. US) who eat “light” processed foods.
It is clear from the wealth of evidence presented that understanding the mechanisms of PAF/PAF-R signalling in health and disease has yet to be fully elucidated. However, the discovery of various PAF and PAFLL agonists and antagonists, the role of the PAF metabolic enzymes in diseases, solving the human PAF-R structure, and identifying PAF signalling mechanisms independent of the PAF-R are some of the many major achievements in current PAF research. PAF is clearly linked to inflammation and CVD.
