Histone deacetylase inhibitors
U.S. Patent 10,172,821 (January 8, 2019)
James Elliot Bradner and Ralph Mazitschek
Abstract: In recognition of the need to develop novel therapeutic agents, the present invention provides novel histone deacetylase inhibitors. These compounds include an ester bond making them sensitive to deactivation by esterases. Therefore, these compounds are particularly useful in the treatment of skin disorders. When the compounds reaches the bloodstream, an esterase or an enzyme with esterase activity cleaves the compound into biologically inactive fragments or fragments with greatly reduced activity Ideally these degradation products exhibit a short serum and/or systemic half-life and are eliminated rapidly. These compounds and pharmaceutical compositions thereof are particularly useful in treating cutaneous T-cell lymphoma, neurofibromatosis, psoriasis, hair loss, skin pigmentation, and dermatitis, for example. The present invention also provides methods for preparing compounds of the invention and intermediates thereto.

Abstract: The invention relates to methods of treating protein degradation disorders, such cellular proliferative disorders (e.g., cancer) and protein deposition disorders (e.g., neurodegenerative disorders). The invention provides methods and pharmaceutical compositions for treating these diseases using aggresome inhibitors or combinations of aggresome inhibitors and proteasome inhibitors. The invention further relates to methods and pharmaceutical compositions for treating multiple myeloma. New HDAC/TDAC inhibitors and aggresome inhibitors are also provided as well as synthetic methodologies for preparing these compounds.
Methods, compositions, and kits for treating pain and pruritis
U.S. Patent 10,179,116 (January 15, 2019)
Bruce P. Bean and Clifford J. Woolf
Abstract: The invention features a method for inhibiting one or more voltage-gated ion channels in a cell by contacting the cell with (i) a first compound that activates a channel-forming receptor that is present on nociceptors and/or pruriceptors; and (ii) a second compound that inhibits one or more voltage-gated ion channels when applied to the internal face of the channels but does not substantially inhibit said channels when applied to the external face of the channels, wherein the second compound is capable of entering nociceptors or pruriceptors through the channel-forming receptor when the receptor is activated. The invention also features a quarternary amine derivative or other permanently or transiently charged derivative of a compound that inhibits one or more voltage-gated ion channels when applied to the internal face of the channels but does not substantially inhibit said channels when applied to the external face of the channels.

Multi-segment reinforced actuators and applications
U.S. Patent 10,184,500 (January 22, 2019)
Kevin Galloway, Conor Walsh, Donal Holland, Panagiotis Polygerinos, Tyler Clites, Paxton Maeder-York, Ryan Neff, Emily Marie Boggs, and Zivthan Dubrovsky
Abstract: A multi-segment reinforced actuator includes (a) a soft actuator body that defines a chamber and (b) a plurality of distinct reinforcement structures on or in respective segments of the soft actuator body. First and second reinforcement structures are respectively configured to produce a first and second actuation motions, respectively, in first and second segments of the soft actuator or body when fluid flows into or out of the chamber. The actuation motions are selected bending, extending, expansion, contraction, twisting, and combinations thereof; and the first actuation motion differs from the second actuation motion. The actuator can be used, e.g., to facilitate bending of the thumb with corresponding bending, extending, expansion, contraction, and twisting actuation motions.
