This research demonstrates that the Ti(PLB)2 complex in solution exhibits a maximum absorption wavelength of 500 nm, the complex has a composition of 1:2, remains stable after 3 minutes at pH=5. It shows linear concentration in the range of 2x10-6- 9x10-6 M, with ε = 5.47x105and a stability constant is 8.6x104. The research results indicate that the Ti(PLB)2 complex can be utilized for titanium analysis in solution, as evidenced by barrier ions and repeatability. The Ti(PLB)2complex showed inhibition of S. aureus bacteria. Furthermore, it inhibited the α-glucosidase enzyme in silico through computational models. Calculation results show that the structure of the Ti(PLB)2 complex is pose 159, which is well bound to the 3TOP enzyme, with ΔGo = -7.66 Kcal.mol1and inhibition constant, Ki=2.43µM, in-depth analysis shows that the complex inhibits the 3TOP enzyme uncompletely. Research pharmacokinetics as drugs, ADMET showed that the complex was less soluble in water (logs and log D) and pharmacological parameters, including drug absorption, drug distribution, drug metabolism, drug excretion and drug toxicity were all within allowable limits. The Ti(PLB)2 complex exhibits strong inhibitory activity against α-glucosidase with an IC50 value of 48.47µM. This research enhances our understanding of how Plumbagin complexes with metal ions can be used for various purposes.
