Misuse of antibiotics led to the world wide spread of antimicrobial resistance threatening human lives. The notable resistance of bacterial cells to antibiotics and immune system is the difficulty associated with biofilm-linked illnesses. Natural products from plant origin with antibiofilm activity could provide more therapeutic activity with fewer adverse effects.

Three new furanosesterterpene tetronic acids, sulawesins A-C (1-3), were isolated from a Psammocinia sp. marine sponge, along with the known compounds ircinins-1 (4) and -2 (5). Although ircinins-1 and -2 were previously isolated as (+)- or (-)-enantiomers from marine sponges, we isolated them as enantiomeric mixtures.

(BC) Birdwood oleogum resin is an ancient remedy of inflammation processes known since Ancient Egyptian time. Of boswellic acids, 3-acetyl-11-keto-β-boswellic acid (AKBA) is the most potent anti-inflammatory active principle. Liquisolid systems of the biologically active fraction of BC oleogum resin were prepared for improving dissolution properties using low dose oral delivery to achieve enhanced anti-inflammatory activity, in comparison with the standard oral anti-inflammatory; Indomethacin.

Context: Boswellia species are trees (family: Bruseraceae) found in India, Northern Africa and the Middle East.

Objective: This study aims at formulating low dose biologically active fraction from the oleogum resin of Boswellia carterii (BC) in transdermal (TD) microemulsions (MEs) to acquire promoted anti-inflammatory efficacy.

Materials And Methods: The bioactive fraction of the oleogum resin of BC was tested for solubility in different components.

The purpose of the present study is to formulate Glycyrrhiza glabra root and rhizome aqueous ethanolic extract in microemulsion carrier systems intended for transdermal delivery of incorporated antioxidant actives, flavonoids and polyphenols. The results obtained reveal that the microemulsion system ME3 possesses optimum properties regarding drug content (flavonoids and polyphenols), viscosity, pH, particle size and polydispersity index, zeta potential, stability, permeation of actives and hence possesses high in vitro and ex vivo antioxidant efficacy. These results indicate also that this microemulsion shows approximately 13-fold higher ex vivo antioxidant capacity compared with the liquorice extract solution.
