Patent number: 11786481Abstract: Methods and compounds are disclosed for wound healing by modulating autophagy. A formulation for modulating autophagy comprises a first modulating compound (FAM) selected from compounds having the general structure (I): wherein: L represents a linker selected from —C?C—, (a tolan), —CH?CH— (a stilbene, preferably trans); or —CRa?CRb— a stilbene derivative; where Ra and Rb are independently H or phenyl optionally substituted with —(R3)p or —(R4)q; R1 to R4 are independent substituents at any available position of the phenyl rings, preferably at 3, 3?, 4, 4?, and/or 5, 5?; and m, n, p, and q are independently 0, 1, 2, or 3 representing the number of substituents of the rings, respectively, but at least one of m or n must be ?1. Each R1 to R2 is independently selected from substituents described herein, including but not limited to hydroxyl, alkoxy, halo, halomethyl and glycosides. The formulation may also include an auxiliary autophagy modulating compound (AAM) as described herein.Type: GrantFiled: April 2, 2021Date of Patent: October 17, 2023Assignee: BioMendics, LLCInventors: Chun-che Tsai, Karen M.

Publication number: 20220296538Abstract: Described are methods for disinfecting a physical or biological surface by contact with an antimicrobial formulation comprising a substituted tolan compound, the substitutions being, for example, one or more alkoxy, (e.g., methoxy) and hydroxy substituents at one or both phenyl rings of the tolan. The compounds and methods are -static and/or -cidal, depending on dose and suspected microbe. Suspected pathogenic microbes include Gram negative bacteria, such as P. aeruginosa and E. coli, Gram positive bacteria, such as S. aureus, including MRSA, and fungal pathogens, such as Candida genus and C. albicans. Also described are methods for inhibiting or disrupting biofilm formation of a microbe or microbes.Type: ApplicationFiled: June 6, 2022Publication date: September 22, 2022Applicant: BioMendics, LLCInventors: Karen M.

Patent number: 7094809Abstract: The present invention provides a method of inhibiting the formation of infectious herpes virus particles, particularly infectious herpes simplex virus (HSV) particles, in a host cell. The method involves administering an effective amount of a hydroxylated tolan, particularly a polyhydroxylated tolan, to a herpes virus infected host cell. The present invention also provides a method of treating a herpes virus infection, particularly an HSV infection. The method comprises administering a topical composition comprising a therapeutically effective amount of a hydroxylated tolan to a herpes virus-infected site. The present invention also relates to a topical composition for treating a herpes virus infection selected from the group consisting of an HSV infection, a cytomegalovirus infection, and a varicella zoster virus infection. The present invention also provides a method of treating a subject infected with Neisseria gonorrhea.Type: GrantFiled: June 11, 2003Date of Patent: August 22, 2006Assignees: Northeastern Ohio Universities College of Medicine, Kent State UniversityInventors: John Docherty, Chun-che Tsai
