Abstract

Integrase is an important molecular target for HIV transmission. The function of integrase inhibitors in overcoming wild-type mutant resistance provides new advances in research. This study aimed to determine the physicochemical properties of 4-amino-1-hydroxy-2-oxo-1,8-naphthyridine-3-carboxamide derivative compounds on integrase enzyme inhibitory activity for HIV-1 treatment based on the QSAR equation, to determine the ligand-receptor hydrogen bond interaction through molecular relationships, to identify the features that drive the selectivity and activity of compounds targeting the integrase enzyme, to conduct virtual screening, and to predict toxicity and pharmacokinetic profiles in silico. QSAR descriptors, molecular docking, pharmacophore features, and virtual screening were calculated with MOE 2009.10 and statistical analysis with the SPSS Statistics 17.0 program. Then pharmacophore docking was performed on two selected compounds from the ZINC database, toxicity tests were performed with Toxtree and AdmetSAR, and pharmacokinetic profiles were determined with PreADMET. The QSAR model showed the best equation: Log (1/IC50) = -1.72 -0.983235703 Mr +0.146570594 AM1_Dipole +0.0019 AM1-HF -0.0895 log S +0.0000 AM1_Eele. The best scoring value in compound 5e is -78.5465. Both compounds have been predicted for suitability and safety, as well as their pharmacokinetic profiles.

Abstract

The authentication of lipid sources in cosmetic products is essential due to regulatory, ethical, and religious concerns, particularly regarding the potential presence of porcine-derived ingredients. This study aimed to evaluate the applicability of Fourier Transform Infrared (FTIR) spectroscopy combined with Principal Component Analysis (PCA) for differentiating lipid profiles in olive oil–based facial mask formulations. Reference lipids, including porcine fat and olive oil, as well as lipid extracts from five commercial cosmetic products, were analyzed using FTIR spectroscopy within the mid-infrared region (4000–650 cm⁻¹). Characteristic absorption bands corresponding to triglyceride structures were observed in all samples, while differences between lipid sources were primarily identified within the fingerprint region (1500–1000 cm⁻¹). PCA was applied to enhance spectral discrimination and revealed clear separation between porcine fat and olive oil along the principal components. Most cosmetic samples (HCN, LTL, NR, and QN) were positioned closer to the olive oil reference, whereas one sample (MDG) showed spectral proximity to porcine fat. However, these results reflect spectral similarity rather than definitive confirmation of lipid origin. The findings indicate that FTIR spectroscopy combined with chemometric analysis can provide a rapid and non-destructive approach for preliminary screening of lipid sources in cosmetic matrices. Nevertheless, due to the limited number of samples and the complexity of cosmetic formulations, further studies incorporating broader sample sets and confirmatory analytical methods are required to support its application in halal authentication and quality control.
