20180273469 · 2018-09-27 ·

A pharmaceutical composition can include: a marmelin analog compound, and a pharmaceutically acceptable carrier having the compound. The compound can be present in a therapeutically effective amount to treat or inhibit a disease state. The disease state can be cancer. The cancer can be selected from brain cancers, head and neck cancers, thyroid cancers, gastrointestinal cancers, esophageal cancers, stomach cancers, pancreatic cancers, liver cancers, colo-rectal cancers, lung cancers, kidney cancers, prostate cancers, bladder cancers, testicular cancers, breast cancers, ovarian cancers, cervical cancers, and melanomas. The carrier includes a cyclodextrin, which may form a complex with the compound. The compounds and compositions can be used to treat or inhibit progression of cancers. Colo-rectal, bladder, and prostate cancers are examples of some of the cancers that can be treated with the marmelin analog compounds.

Depolymerization of lignin using metal incorporated mesoporous silicate catalysts

Provided is a process for depolymerizing lignin, the process comprising exposing a liquid feed comprising lignin and a solvent to a metal-incorporated solid mesoporous silicate catalyst under conditions sufficient to depolymerize the lignin to produce one or more aromatic monomers.

FUNCTIONALIZED CYANOSILANE AND SYNTHESIS METHOD AND USE THEREOF
20180141964 · 2018-05-24 ·

The present teachings relate to a functionalized silyl cyanide and synthetic methods thereof. As an example, the method may include adding a raw material silane and a cyanide source MCN in an organic solvent to produce the functionalized silyl cyanide in the absence of catalyst or in the presence of a metal salt catalyst. The functionalized silyl cyanide may be used in the reactions that classic TMSCN participates in, to synthesize important intermediates (e.g., cyanohydrin, amino alcohols and -amino nitrile compounds), with improved reactivity and selectivity. The cyanosilyl ether resulted from the nucleophilic addition of functionalized silyl cyanide to aldehyde or ketone may undergo intramolecular reaction under appropriate conditions to transfer the functional groups on silicon onto the other parts of the product linked to silicon. Such a functional group transfer process may increase the synthesis efficiency and atom economy, as well as afford products unobtainable using traditional TMSCN.
