Abstract

Introduction: Alveolar osteitis is the most common complication after tooth extraction, which occurs 2 to 4 days after and causes disruption of wound healing. Pucuk Bungur/Queen’s crepe myrtle  (Lagerstroemia speciosa) and aloe vera have biological and pharmacological benefits in experimental animals: antimicrobial, anti-inflammatory, and antioxidant. They also affect the wound healing process.  These benefits are a good combination as an alternative remedy for alveolar osteitis treatment. This study was aimed to analyse the effect of Lagerstroemia speciosa compared to aloe vera extracts gel on the wound healing process after tooth extraction in Sprague-Dawley mice with alveolar osteitis. Methods:  This research was an experimental laboratory. Twenty-seven Sprague-Dawley mice were randomly divided into three groups. The first group was the osteitis (control) group treated with 1:1000 adrenaline insertion for 1 minute on the left maxillary first molars socket; the second group was the osteitis group administered with the application of Lagerstroemia speciosa, and the third group was the osteitis group administered with the application of aloe vera gel. Normal mice in the control group were not given any treatment, only osteitis mice. The interleukin-6 level was examined after, and the number of osteoblasts was also calculated on the 3rd, 5th and 14th day after the necropsy was performed. Data were analysed with one-way ANOVA to compare the effectiveness of wound healing of alveolar osteitis in each group. Results: From the data analysis, the osteitis group applied with  Lagerstroemia speciosa gel had good activity in the inflammation phase of the healing process of alveolar osteitis compared to other groups. Conclusion: Lagerstroemia speciosa can be a potential alternative treatment to reduce inflammation and accelerate the healing of osteitis because it shortens the inflammatory phase and accelerates collagen production in wound healing.

Abstract

Physalis angulata was known for its pharmacological potential, including antioxidant activity, yet the specific bioactive compounds responsible for enhancing endogenous antioxidant enzymes, such as superoxide dismutase 1 (SOD 1), remained unclear. This study aimed to identify and evaluate the active compounds of P. angulata as natural SOD 1 activators using an In silico molecular docking approach. Forty-nine ligands derived from the active constituents of P. angulata were screened based on Lipinski’s Rule of Five and ADMET properties. Molecular docking was performed using the SOD 1 protein (PDB ID: 5YTO), and docking validation yielded an RMSD value of 0.005 Å. Among the test ligands, withanolide exhibited the most favorable binding energy (−7.011 kcal/mol) and the lowest inhibition constant (7.0 pM), forming strong interactions with key catalytic residues of the enzyme. These findings indicated that withanolide had promising potential as a natural SOD 1 activator, providing a basis for future antioxidant drug discovery.
