Rated the possible for CYP- and/or P-gp-mediated NDIs, NDIs associated with other drug transporters excepting P-gp, phase II metabolism, and transporters-mediated renal excretion are still missing [46]. Furthermore, the discrepancy among in vitro estimation and in vivo research for NDIs (i.e., lack of in vitro n vivo correlation), and distinction with animal models and humans regarding the expression of drug transporters and also the consequent NDIs can also impede the exact prediction of NDIs in clinical [111]. Furthermore, thinking of that, on occasion, drug concentration in blood, plasma, or CSF will not represent the concentration into the brain tissues or ISF, NDIs inside the BBB and BCSFB may perhaps not drastically alter its plasma concentration, whereas NDIs can impact the drug concentration within the brain and its efficacy against brain disorders [4,112]. For that reason, for the precise determination and prediction of NDIs, other sorts of measuring approaches like brain imaging by using positron emission tomography and magnetic resonance spectroscopy are regarded as as a far more adequate and relevant tool instead of drug quantification by means of blood or CSF collection, in KDM2 Synonyms recent times [16,113]. Furthermore, quite a few current studies reported that deep understanding models, sorts of in silico technique for prediction of NDIs, can exhibit enhanced accuracy and more effective performance, insisting that these models may possibly play a key role in future research, drug discovery, and improvement processes to estimate feasible interactions amongst all-natural compounds and new drugs for brain problems [11416].Author Contributions: Conceptualization, B.K., J.-Y.L., E.K.P., K.-T.K., J.-S.B.; investigation, B.K., J.-Y.L., K.-T.K.; writing–original draft preparation, B.K., J.-Y.L., K.-T.K.; writing–review and editing, E.K.P., K.-T.K., J.-S.B.; visualization, B.K., J.-Y.L.; funding acquisition, J.-Y.L., E.K.P., K.-T.K., J.-S.B.
