  • Publication number: 20230276794
    Abstract: Mesh materials for the controlled release of antimicrobial and antiviral compounds, with high antiviral activity and efficacy, predominantly against coronavirus, and a method for producing mesh materials with inclusion compounds of bisbiguanide:cyclodextrin, using mesh materials selected from polymers, fibers, nonwoven fabric, fabrics, paper and cellulose, individually or in combination, or a combination of one or more of these mesh materials with adhesives. The mesh materials impregnated, extruded, saturated, coated or laminated with inclusion compounds have been shown to be effective in the deactivation/destruction of viral particles. In fabrics, the inclusion compounds exhibited virucidal activity for all of the viruses in the coronavirus group for contact times of above 2 minutes, with the effect thereof lasting for more than 30 days. The mesh materials for controlled release of antivirals have displayed activity which is up to 1000 times more effective than the use of unencapsulated chlorhexidine.

    Abstract: We describe preparation of compounds of an AT1 receptor antagonist(s) and Angiotensin (1-7), for example, Angiotensin-(1-7) losartanate and analogues thereof, and/or mixtures of these systems, pharmaceutical compositions thereof and use of their derivative products. Cyclodextrins and derivatives thereof may be used for the micro-encapsulation of compounds, for example, Angiotensin (1-7) losartanate, liposomes and biodegradable polymers and/or mixtures of these systems and/or derivative products for the obtainment of nano- or microparticles as controlled or sustained release devices of Ang-(1-7) losartanate and analogues and/or mixtures thereof. The compounds may be used as agents for treating or preventing hypertension, cardiovascular diseases, heart hypertrophy, heart failure, coronary diseases, such as angina pectoris, endothelial disorder or endothelial lesions, as a consequence, for example, of atherosclerosis processes or in association with diabetes mellitus.
