ABSTRACT
Background: Background: Staphylococcus aureus is a gram-negative bacterium that can build strong biofilms on biotic and abiotic surfaces, quickly acquire drug resistance mechanisms, and cause major issues with the treatment of hospital infections. The creation of new therapeutic options has become important due to the limited supply of new antibacterial medications. One of the main sources of bioactive molecules is medicinal plants, and monolaurin is a naturally occurring substance with a variety of biological functions. In light of this, the goal of this study was to assess monolaurin's antibiofilm activity against S. aureus. Methods: Using the AutoDock programme, a docking study of monolaurin against Clf A (clumping factor A) was carried out, and Pymol software was used to evaluate the generated hydrogen bonds in the docked complex. This study demonstrates the positive potential of monolaurin as an antibacterial product and lends support to upcoming pharmacological research on this molecule with an eye toward its therapeutic use. Results: Research was done to support the theoretical absorption of monolaurin in this work and in silico. It was feasible to forecast if the monolaurin molecule may be produced as a medication based on the values of the physical-chemical parameters evaluated using the online tool Swiss ADME. Conclusion: The compound monolaurin demonstrated good receptor ClfA binding affinity with an estimated binding energy of kcal/mol. Natural anti-staphylococcal chemical monolaurin was used as a possible medicine for treating staphylococcal infections in humans by carrying out drug design studies for S. aureus.
ABSTRACT
The purpose of this study is to evaluate the photostability of nifedipine (NIF) in solid monolaurin (ML)-based matrix and the micellar solutions thereof. NIF loaded-ML matrices at concentrations of 1:1, 1:4 and 1:9 w/w were prepared using a fusion-high shear homogenization method and characterized using differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). The absence of an endothermic melting peak at 173° C in the 1:4 and 1:9 w/w NIF-ML matrices indicates that NIF is in an amorphous state. The 1:1 w/w NIFML matrix showed an endothermic peak at 154° C indicating the transformation of NIF into polymorph III. Stability-indicating HPLC method was developed and validated to quantify NIF and its degradation product. Photoexposed 1:1, 1:4 and 1:9 w/w NIF-ML matrices exhibited 2.1, 4.6 and 17 fold slower first-order degradation rates as compared to the NIF powder. After 24 days of exposure, the percent drug remaining in the 1:9 w/w NIF-ML matrix was 85% as compared to only 5% in pure NIF powder. The micellar solutions exhibited 7-fold slower degradation kinetics than the aqueous solution. The results of this study indicate that the stability of nifedipine can be improved by formulation into monoglycerides matrix.
