Murugappan Muthukumar has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10736863
    Abstract: Described herein are methods of inhibiting or reversing the progression of cataract formation or presbyopia in an eye by administering a bifunctional molecule comprising a substituted or unsubstituted amine, succinimide, carboxylic acid, isocyanate, isothiocyanate, sulfonyl chloride, aldehyde, carbodiimide, acyl azide, anhydride, fluorobenzene, carbonate, N-hydroxysuccinimide ester, imidoester, epoxide or fluorophenyl ester covalently linked to a molecular bristle. Both presbyopia and cataracts are caused by aggregation of the soluble crystalline lens proteins called the crystallins.
    Type: Grant
    Filed: November 11, 2016
    Date of Patent: August 11, 2020
    Assignee: UNIVERSITY OF MASSACHUSETTS

  • Patent number: 9283237
    Abstract: Described herein are methods of inhibiting or reversing the progression of presbyopia in an eye by administering a ?L-crystallin electrostatic interaction inhibitor. Presbyopia is caused by aggregation of the soluble crystalline lens proteins called the crystallins, particularly ?L-crystallin. It has been found that the aggregation of ?L-crystallin is an electrostatic phenomenon and that electrostatic interaction inhibitors can be employed to prevent the formation of ?L-crystallin aggregates as well as to deaggregate already formed aggregates.
