Patent number: 11155562Abstract: The present invention provides halichondrin analogs, such as compounds of Formula (I). The compounds may bind to microtubule sites, thereby inhibiting microtubule dynamics. Also provided are methods of synthesis, pharmaceutical compositions, kits, methods of treatment, and uses that involve the compounds for treatment of a proliferative disease (e.g., cancer). Compounds of the present invention are particularly useful for the treatment of metastatic breast cancer, non-small cell lung cancer, prostate cancer, and sarcoma. The included methods of synthesis are useful for the preparation of compounds of Formula (I)-(III) along with naturally occurring halicondrins (e.g., halichondrin B & C, norhalichondrin A, B, & C, and homohalichondrin A, B, & C). Also included are methods for interconverting between the halichondrins, norhalichondrins, and homohalichondrins and their unnatural epimers at the C38 ketal stereocenter through the use of an acid-mediated equilibration.Type: GrantFiled: January 17, 2020Date of Patent: October 26, 2021Assignee: President and Fellows of Harvard CollegeInventors: Yoshito Kishi, Atsushi Ueda, Akihiko Yamamoto, Daisuke Kato

Patent number: 9551518Abstract: A first expansion valve is provided in a first refrigerant circulation passage through which the refrigerant discharged from a compressor is able to circulate by passing sequentially through an external heat exchanger and an evaporator and returning to the compressor. A second expansion valve is provided in a second refrigerant circulation passage through which the refrigerant discharged from the compressor is able to circulate by passing sequentially through an auxiliary condenser and the external heat exchanger and returning to the compressor.

Patent number: 7069960Abstract: A control technique is capable of adjusting a weight of a pile fabric by adjusting consumption of a pile warp at a proper range with a more simplified system. In a pile loom, a tolerance relative to a value associated with consumption of the pile warp is set, and the value associated with consumption of the pile warp is measured during a pile weaving period. If the value associated with consumption of the pile warp exceeds the tolerance, the weaving condition parameter associated with the weight of the pile is corrected in a direction to approach a target value of the weight of a pile fabric.Type: GrantFiled: November 21, 2003Date of Patent: July 4, 2006Assignee: Tsudakoma Kogyo Kabushiki KaishaInventors: Akihiko Nakada, Akihiko Yamamoto, Masato Matsumoto, Tomokazu Ishita
