Vesicular carriers of drugs are popular for specific targeting and delivery. The most popular vesicles among these are liposomes. However, they suffer from some inherent limitations. In this work, alternative vesicles with enhanced stability, i.e., niosomes and bilosomes have been prepared, characterized, and their delivery efficiency studied. Bilosomes have the additional advantage of being able to withstand the harsh environment of the gastrointestinal tract (GIT). The taurine-derived bile salt (NaTC) was incorporated into the bilosome bilayer. The inspiration behind NaTC insertion is the recent reports on antiaging action and immune function of taurine. Fluorescence probing was used to study the vesicle environment. The entrapment and subsequent release of the important cAMP-specific PDE4 inhibitor/drug Rolipram, which has antibreast cancer properties, was assessed on the breast cancer cell line MCF-7. Rolipram has important therapeutic applications, one of the most significant in recent times being the treatment of Covid-19-triggered pneumonia and cytokine storms. As for cancer chemotherapy, the localization of drug, targeted delivery, and sustained release are extremely important issues, and it seemed worthwhile to explore the potential of the bilosomes and niosomes to entrap and release Rolipram. The important finding is that niosomes perform much better than bilosomes in the hormone-responsive breast cancer mileau MCF-7. Moreover, there was a 4-fold decrease in the IC50 of Rolipram encapsulated in niosomes compared to Rolipram alone. On the other hand, bilosome-encapsulated Rolipram shows higher IC50 value. The results can be further understood by molecular docking studies.
