Additionally disclosed is the synthesis of a novel amorphous, nanostructured bimetallic compound of dysprosium erbium borate trihydrate used in this formulation.
专利号:US-12221452-B2 优先权日:2017-10-04 标题:Synthesis of cantharidin 发明人:DAVIDSON MATTHEW GENE; EKLOV BRIAN MATTHEW; WUTS PETER; LOERTSCHER BRAD MELVIN; SCHOW STEVEN R 权利人:VERRICA PHARMACEUTICALS INC 摘要:The invention provides synthetic methods for the preparation of cantharidin and analogs thereof. In one aspect, the invention provides an improved Diels-Alder cycloaddition to generate a key intermediate en route to cantharidin and analogs thereof. In certain embodiments, the new Diels-Alder reaction involves reacting Compound (2) in the presence of furan, and in the absence of acid or increased pressure, in an aprotic polar solvent with slight warming, to yield Compound (1) in favorable yield and exo-endo ratio. In another aspect, the invention also provides a new Diels-Alder reaction between compounds of Formula (III) and furan to yield compounds of Formula (IV), which can then be transformed into cantharidin or analogs thereof. In yet another aspect, the invention describes a new palladium-mediated carbonylation providing another key intermediate en route to cantharidin and analogs thereof. In addition to synthetic methods, present invention also provides compounds (i.e., intermediates) useful in the synthesis of cantharidin and analogs thereof. Compounds provided herein may have biological activity, and therefore may be used in the treatment of diseases or conditions (e.g., infectious diseases and skin conditions).

Attaching silicon-containing compounds to a surface comprises providing a silicon-containing compound having two or more leaving groups, and a first functional compound comprising at least one nucleophilic group, contacting the silicon-containing compound and the functional compound with a surface of a substrate having nucleophilic sites and exposing the silicon-containing compound, the functional compound and the surface of the substrate to microwave radiation.
专利号:WO-2017137818-A1 优先权日:2016-02-12 标 题 :Synthesis and application of an antimicrobial active 发明人:K RAKESH RATNAM; SARVIYA SAMIR 权利人:SALICYLATES & CHEMICALS 摘要:The disclosure Synthesis & Application of a Novel Antimicrobial active provides a method of synthesis of organic complex starting from fatty acid with a free base bioactive molecule containing nitrogen atoms. The reaction is usually conducted in refluxing alcohol. The product is synthesized by a acid-base reaction whereby the acid molecule is capable of donating a proton, to the free base molecule resulting in the formation of the desired complex. These complexes are very effective antimicrobial active against a variety of bacteria, fungi, protozoa, helminths and viruses. The process is suitable for large-scale synthesis and involves simple and high-yielding techno feasible chemical transformations using low-cost commercially available raw materials. The complex has wide spread use in human personal care, industries and household applications, as the disclosed chemical has antimicrobial activity against gram positive, gram negative bacteria, yeast, mold, fungi.
专利号:US-11155562-B2 优先权日:2014-06-30 标 题 :Synthesis of halichondrin analogs and uses thereof 发明人:KISHI YOSHITO; UEDA ATSUSHI; YAMAMOTO AKIHIKO; KATO DAISUKE 权利人:HARVARD COLLEGE 摘要: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.
