  • Patent number: 10556910
    Abstract: 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.

  • Publication number: 20190392229
    Abstract: To provide a parking space recognition apparatus that can reduce a processing load for detecting the parking space. The parking space recognition apparatus recognizes a parking space by using images generated by four cameras to be mounted on a vehicle. In the parking space recognition apparatus, an image acquisition part acquires the images generated by the cameras. A detection setter selects the cameras to be used for detecting the parking space from among the cameras based on a traveling state of the vehicle. A parking space detector acquires the images generated by the cameras selected by the detection setter from the image acquisition part, and detects the parking space from the acquired images.

  • Patent number: 10317654
    Abstract: A variable magnification optical system includes: a first lens group having positive refractive power and arranged closest to an object; a negative lens group having negative refractive power; a positive lens group which has positive refractive power, which includes at least one lens that moves integrally with an aperture stop, and which is arranged closer to an image than the negative lens group; and a focusing group arranged between the negative lens group and the positive lens group. When varying magnification, distances between the first lens group and the negative lens group and between the negative lens group and the positive lens group are changed. When focusing, distances between the focusing group and a lens facing an object-side of the focusing group and between the focusing group and a lens facing an image-side of the focusing group are changed. A predetermined conditional expression is satisfied.
