Rated the prospective 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]. Additionally, the discrepancy amongst in vitro estimation and in vivo studies for NDIs (i.e., lack of in vitro n vivo correlation), and distinction with animal models and humans relating to the expression of drug transporters as well as the consequent NDIs also can impede the precise prediction of NDIs in clinical [111]. In addition, thinking about that, on occasion, drug concentration in blood, plasma, or CSF does not represent the concentration into the brain tissues or ISF, NDIs inside the BBB and BCSFB may not considerably transform its plasma concentration, whereas NDIs can affect the drug concentration inside the brain and its efficacy against brain disorders [4,112]. For that reason, for the precise determination and prediction of NDIs, other types of measuring approaches like brain imaging by using positron emission tomography and magnetic resonance spectroscopy are viewed as as a additional adequate and relevant tool HDAC10 Storage & Stability alternatively of drug quantification through blood or CSF collection, in recent times [16,113]. Furthermore, many current studies reported that deep learning models, kinds of in silico system for prediction of NDIs, can exhibit improved accuracy and much more efficient functionality, insisting that these models may perhaps play a important function in future study, drug discovery, and improvement processes to estimate doable interactions involving organic compounds and new drugs for brain issues [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.
