Publication number: 20230125280Abstract: Novel tetrahydroisoquinoline derivative compounds are disclosed herein that may be used as an active ingredient for a pharmaceutical composition, and in particular, for a pharmaceutical composition useful for preventing or treating a disease or condition responsive to modulation of the contractility of the skeletal sarcomere. This may be accomplished, for example, by modulation of the troponin complex of the fast skeletal muscle sarcomere through one or more of fast skeletal myosin, actin, tropomyosin, troponin C, troponin I, and troponin T, and fragments and isoforms thereof. The tetrahydroisoquinoline derivative compounds can thus be used as an agent for preventing or treating 1) neuromuscular disorders, 2) disorders of voluntary muscle, 3) CNS disorders in which muscle weakness, atrophy, and fatigue are prominent symptoms, 4) muscle symptoms stemming from systemic disorders, and 5) dysfunctions of pelvic floor and urethral/anal sphincter muscle.Type: ApplicationFiled: September 13, 2022Publication date: April 27, 2023Inventors: Ippei SATO, Takashi KAMIKUBO, Masanori MIURA, Yuji MATSUSHIMA, Hiroaki TANAKA, Yasuhiro SHIINA, Susumu YAMAKI, Tomoyuki SAITO, Hiroshi KIYOHARA, Munemichi OHE, Kayoko MIHARA, Bradley Paul MORGAN, Fady MALIK, Scott Emile COLLIBEE, Luke ASHCRAFT, Pu-Ping LU, Jeffrey Michael WARRINGTON, Marc GARARD

Patent number: 8835881Abstract: A writing area of a sample is divided into a plurality of stripes having a width corresponding to an area density of a pattern to be written on the sample with a charged-particle beam. The writing is stopped when writing of at least one stripe is terminated, and a drift amount is measured. An irradiation position of the charged-particle beam is corrected with the use of the drift amount. When the average value of the area density is more than a predetermined value, a stripe has a width smaller than the reference width, and when the average value of the area density is less than the predetermined value, the stripe has a width larger than the reference width. The width of the stripe is preferably a width corresponding to the variation of a drift from the beginning of irradiation with the charged-particle beam.Type: GrantFiled: June 11, 2013Date of Patent: September 16, 2014Assignee: NuFlare Technology, Inc.Inventor: Takashi Kamikubo
