Yet, the absence of established systemic and brain pharmacokinetic (PK) parameters at relevant pre-clinical doses presents a significant knowledge gap. In vitro assays examined brain tissue binding and metabolic stability. The findings highlight metformin's rapid brain entry, minimal binding, and metabolic stability.

Conversely, and interestingly, UGTs present in the bladder can protect against accumulation of toxins since they are highly expressed on the surface of bladder tissue, particularly in females where it is postulated that the lower incidence of bladder cancer is related to increased UGT isoform activity.

While I would agree that efficiency metrics are integral to the philatelic aspects of modern drug discovery, I don’t believe that YL2018 actually presents a single convincing example of efficiency metrics being used for decision making in a specific drug design project. Increasing the extent of ionization may also compromise permeability.

22 Figure 17 Conclusion We hope you find this vignette on the metabolism of five membered nitrogen containing heterocycles a useful resource. There is much to be learnt from the pathways described above but in general, the more nitrogens present in your ring, the less likely you are to see Phase I type oxidations of the ring itself.

In fact, CYP2C8, CYP1A2, CYP2B6, CYP2C9, and CYP2D6 all contribute to adagrasib’s metabolism at steady-state. A poster presentation at the 2022 ISSX meeting on metabolism of MRTX849 revealed three circulating metabolites, M11, M55a and M68, at > 10% following a single oral dose. Br J Pharmacol.
