  • Patent number: 11884714
    Abstract: The invention described herein is based in part on the discovery of a protein/peptide crosslink, which introduces fluorescent properties, and which has been applied to synthesize analogues of melanocortin and amanitin as choice peptides to be explored in the context of isoindole peptides. Without limitation, it is expected that those trained in the art of peptide synthesis and stapling would appreciate the consequences of this invention such that other peptides of varied length can be similarly constrained by isoindole staples as featured herein.

  • Publication number: 20220218852
    Abstract: This application relates to compounds of Formula (I): [targeting peptide]-N(R1)—X1(R2)L1-[linker]-RXn1 (I). The targeting peptide is cyclo[L-Phe-L-Tyr-L-Lys(iPr)-D-Arg-L-2-Nal-Gly-D-Glu]-L-Lys(iPr). R1 is H or methyl. X1 is an optionally substituted C1-C15 hydrocarbon optionally comprising heteroatoms. R2 is C(O)OH or C(O)NH2. L1 is a linkage (thiolether, amide, maleimide-thiol, triazole). The linker has a net negative charge at physiological pH and is a linear or branched chain of 1-10 units of X2L2 and/or X2(L2)2, wherein: each X2 is, independently, an optionally substituted C1-C15 hydrocarbon optionally comprising heteroatoms; and each L2 is a linkage. The linker optionally further comprises an albumin binder bonded to an L2. Each RX is a radiolabelling group linked through a separate L2, selected from: a metal chelator; a prosthetic group containing trifluoroborate (BF3); or a prosthetic group containing a silicon-fluorine-acceptor moiety.

  • Patent number: 11112126
    Abstract: A device for a sanitary facility, intended for rapidly delivering Domestic Hot Water (DHW) to the supply points without wasting energy. The device according to the invention transfers the DHW rapidly from the source to the user as soon as there is a need for it. The method, which prevents any recirculation, makes it possible, in particular, to save the large amount of energy that is systematically wasted each time the DHW is distributed between its source and the supply points. The device essentially consists of a motorised, relatively powerful pump (2) which channels the DHW from the source (1) and injects it into a pipe with a very small cross-section (3) that conveys the entire flow rate required by the user at a high velocity to the supply point (41). An adapted sensor (5) controls the switching on and off of the motor pump (2) upon each use and controls its flow rate on the basis of the requirements. A single device can be used for supplying multiple supply points.

  • Patent number: 10980600
    Abstract: The method of assisting the production of an implantable unfurlable made to measure device comprises: three-dimensional reconstruction of a complex surface of the cavity in which the device will be implanted; Production of a first finite element mesh of this complex surface; Choosing of generic components of the device; Production of a second finite element mesh of these assembled generic components; Determination of the morphosis parameters for morphosing from the first mesh to a mesh of a set of simple linked volumes which is representative of the part of the cavity, and then deformation of the first mesh by this morphosis; Simulation of a deformation of the second mesh, by inverse morphosis dependent on the determined parameters, to the complex surface, simulating unfurling of the device; Determination of dimensioning of points of interest by projection onto the second deformed mesh; and Generation of a production blueprint plan of the device.
