Patent number: 12084418Abstract: The disclosure relates to novel compounds and methods of use of the compounds to maintain the G?i2 protein in its inactive GDP-bound state. The disclosure describes the knockdown or inhibition of G?i2 negatively regulated migration of breast and ovarian cancer cell lines. The novel compounds inhibit the migratory behavior of PC3, DU145 and E006AA prostate cancer cell lines. Specifically, the novel compounds block the activation of G?i2 in oxytocin-stimulated prostate cancer PC3 cells and inhibits the migratory capability of DU145 cells overexpressing constitutively active form of G?i2, under basal and EGF-stimulated conditions.Type: GrantFiled: December 20, 2021Date of Patent: September 10, 2024Assignees: CLARK ATLANTA UNIVERSITY, INC., GEORGIA TECH RESEARCH CORPORATIONInventors: Shafiq A. Khan, Silvia Caggia, Adegboyega K. Oyelere, Subhasish Tapadar

Publication number: 20200354567Abstract: The invention provides a polymer composition comprising from 50 wt % to 99.9 wt % polymer, from 0.1 wt % to 10 wt % nanocellulose as a first nucleating agent, and from 0.01 wt % to 5 wt % of a second nucleating agent. In some embodiments, the polymer is polylactide, the first nucleating agent is lignin-containing nanocellulose, and the second nucleating agent is a sulfur-containing, oxygenated aromatic molecule. The oxygenated aromatic molecule may be an aromatic sulfonic acid or salt, such as dimethyl 5-sulfoisophthalate. In other embodiments, the sulfur-containing, oxygenated aromatic molecule is lignosulfonic acid. Other variations provide a polymer composition comprising polymer, lignin-containing nanocellulose as a dispersing agent, and additives selected from nucleating agents, compatibilizers, plasticizers, fillers, antioxidants, colorants, or flame retardants.Type: ApplicationFiled: May 22, 2020Publication date: November 12, 2020Applicant: Clark Atlanta UniversityInventors: Kimberly Nelson, Eric A.
