  • Patent number: 11643438
    Abstract: Cyclic depsipeptide-class molecules, referred to herein as persephacins (including analogs thereof), having similarities to aureobasidin A, are described. The persephacins have antimicrobial activity, such as antifungal activity against a diverse range of clinically-relevant fungal pathogens, antiprotozoan parasite activity, and antibacterial activity, and can be used for example in treatments of difficult-to-treat ocular fungal infections at lower concentrations than natamycin. The active compounds may be combined with a secondary compound in a composition.
    Type: Grant
    Filed: July 19, 2019
    Date of Patent: May 9, 2023
    Assignee: The Board of Regents of the University of Oklahoma
    Inventors: Robert H. Cichewicz, Lin Du, Jianlan You, Allison O. Mattes, Shikha Srivastava, Saikat Haldar
  • Publication number: 20220144747
    Abstract: The present disclosure, in at least certain embodiments, is directed to shikimate (shikimic acid) analogues and compositions thereof, devices and kits which contain the shikimate analogues or compositions thereof, and methods of use of the compounds and compositions for treating and neutralizing irritant or odoriferous compounds on animate or inanimate surfaces or in atmospheres.

  • Patent number: 11180452
    Abstract: A method of selectively inhibiting pathogenic microbes includes: providing a compound that is functional as a selective antimicrobial having a structure of Formula 1, or derivative thereof, salt thereof, or stereoisomer thereof, or having any chirality at any chiral center, or tautomer, polymorph, solvate, or combination thereof; and contacting a pathogenic microbe with the compound such that the pathogenic microbe is selectively inhibited; wherein: ring A is a cycloalkyl, heterocycloalkyl, aryl, heteroaryl, or polycycle combination thereof; X is S, SO, or SO2; Y is a linker or bond; Z is CH, CR2, or N; Z1 is C or N to form an imidazopyridine; each Z2, Z3, or Z4 is independently CH, CR2, or N; each Z5 or Z6 is C or CH; each R1, R2, R3 and/or R4 is independently a substituent; m is 0, 1, 2, 3, or 4; and n is zero or a positive integer.

  • Publication number: 20200399218
    Abstract: A compound can have a structure of Formula A, or derivative thereof, salt thereof, or stereoisomer thereof, or having any chirality at any chiral center, or tautomer, polymorph, solvate, or combination thereof: wherein ring A is a phenyl, indolyl, naphthyl, or benzothiazolyl; X is S, SO, or SO2; Y is a linker or bond; Z is CH, CR2, or N; Z1 is C or N to form an imidazopyridine; each Z2, Z3, or Z4 is independently CH, CR2, or N; each Z5 or Z6 is C or CH; each R1, R2, and R3 is independently a substituent, and at least one of R1, R2, or R3 is a substituent other than a hydrogen; m is 0, 1, 2, 3, or 4; and n is 0 or a positive integer. The compounds can have specific substituent patterns.
