Several limitations of traditional reuptake inhibitors, like delayed onset of action, insomnia, and sexual dysfunction, have compelled the search for safer, more effective compounds.
To develop more effective compounds as penetration enhancers, O-acylmenthol derivatives were synthesized by l-menthol and saturated fatty acid, O-ethylmenthol (MET), was also synthesized as a reference compound.
So it is worth developing new, more effective compounds, such as gemini QACs.
Distinguishing between these two scenarios should drive the selection and development of more effective compounds in the future.
According to the literature, fermentation using microorganisms for the production of more effective compounds has been extensively studied.
Paradoxically, adenosine is also an immunosuppressive, vasodilatory and platelet aggregation inhibitor, and the presence of an enzyme that removes such a potentially useful molecule was explained in insects with the production of other more effective compounds counteracting these actions [ 60].
Hence, not only do we have more effective compounds, there are unparalleled opportunities for these to be combined with emerging novel biological agents, supported by the presence of new molecular and imaging methodologies.
Therefore, new families of more effective compounds should be developed and tested in different in vitro and in vivo models to support the translation of anti-TMPRSS4 therapy in clinical settings.
Given that many men are unsuitable for chemotherapy, either because they are elderly or have comorbidities, there is still a pressing need to evaluate better-tolerated and more effective compounds and combinations for the treatment of this disease.
The paucity of models for these proteins is surprising, as these proteins are the targets of a number of invertebrate specific ligands, such as insecticides, and a better understanding of critical binding site features could assist the development of novel, more effective compounds (13, 14).
