    摘要: The present application relates to a compositions and methods comprising or expressing a hevamine A-related MoMo30 protein from Momordica balsamina. The MoMo30 protein is about 30 kDa in size, is stable after being autoclaved at 120° C. for 30 min, resists proteolytic cleavage by trypsin, exhibits mannose-sensitive binding to HIV gp120, exhibits hemagglutinin and chitinase activity, is capable of activating and stimulating T cell proliferation, is capable of preventing infection by HIV-1 or alleviating symptoms in an HIV-1 infected patients, and comprises an amino acid sequence of SEQ ID NO: 4. The MoMo30 protein and/or a nucleic acid encoding the same may be used in methods for preventing or treating microbial infections by HIV, SARS-CoV-2 and other enveloped viruses, as well as other microorganisms comprising cell surface proteins containing glycan residues, such as mannose.

    摘要: The present application relates to a compositions and methods comprising or expressing a MOMO30 protein derived from Momordica balsamina. The MOMO30 protein is about 30 kDa in size, binds coronavirus S protein, is stable after being autoclaved at 120° C. for 30 min, resists proteolytic cleavage by trypsin, exhibits mannose-sensitive binding to coronavirus spike (S) protein, exhibits hemagglutinin and chitinase activity, is capable of activating and stimulating T cell proliferation, is capable of preventing infection by a coronavirus or alleviating symptoms in coronavirus infected patients and comprises the amino acid sequence of SEQ ID NO: 1. The MOMO30 protein and/or a nucleic acid encoding the same may be used in methods for preventing or treating viral infections by coronaviruses and others.

    摘要: The watermelon seed nanoparticles may be synthesized by dissolving powdered watermelon seeds in a solvent to produce a first mixture, adding the first mixture dropwise to boiling water under ultrasonic conditions to produce a second mixture, sonicating the second mixture and drying the second mixture to produce watermelon seed nanoparticles. In an embodiment, the watermelon seeds may be Citrullus lanatus seeds. In an embodiment, the watermelon seed nanoparticles may be included in a pharmaceutical composition, such as an antimicrobial or anti-cancer composition.
