Abstract

Excessive melanin synthesis, often triggered by overexposure to UV rays, is catalyzed by melanogenesis enzymes such as tyrosinase, tyrosinase-related protein 1, and D-dopachrome tautomerase. Derived from natural sources, the flavonoid compound luteolin is explored for its antihyperpigmentation potential. This study assesses luteolin’s efficacy as an antihyperpigmentation agent by analyzing its affinity and bond interactions with melanogenesis enzymes through an in silico approach. Molecular docking, facilitated by HyperChem 8 for test compound optimization and Chimera 1.11.1 for protein preparation, alongside method validation and docking with AutoDockTools 1.5.6, established the protocol’s validity with an RMSD value of ≤3 Å. Docking results reveal luteolin's higher affinity for the target proteins compared to native ligands, with binding energies of -5.63 kcal/mol for tyrosinase, -6.18 kcal/mol for tyrosinase-related protein 1, and -6.54 kcal/mol for D-dopachrome tautomerase. The interaction between luteolin and these proteins involves hydrogen, hydrophobic, electrostatic, and Van der Waals bonds, with amino acid residues His61, Lys129, Arg132 (tyrosinase); His192, His224, Val89 (tyrosinase-related protein 1); and Ile64, Asn73 (D-dopachrome tautomerase) participating in hydrogen bond formation. These findings suggest luteolin’s significant potential as an antihyperpigmentation agent by inhibiting melanogenesis enzymes.

Abstract

Beyond-use date (BUD) is crucial for the stability of injectable preparations. However, there is a knowledge gap and a lack of information regarding BUD determination in injection preparations. Therefore, a systematic review is needed to address the BUD of injection preparations. This study aimed to provide comprehensive insights into the stability, BUD data, and associated implications for injectable preparations through a systematic literature review approach. This study employed a systematic literature review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The inclusion criteria were research articles from national and international journals discussing the BUD of sterile injection preparations published in the last 10 years. Fourteen of the 19 articles related to BUD were selected for analysis. The analysis revealed that the stability of the 19 sterile injection preparations was significantly influenced by the characteristics of the preparation, storage conditions, and type of drug. These factors substantially affect the effectiveness and safety of drugs. Intravenous sterile injections involve several critical steps to ensure the safety and efficacy of the medications used. Adhering to BUD guidelines for intravenous injections is crucial for maintaining drug quality, which can help prevent infections or adverse reactions in patients. The stability of sterile injection preparations, which is influenced by various factors, has direct implications for BUD determination. This review highlights the importance of considering these factors when determining BUD to ensure patient safety.
