More particularly, it relates to a novel, simplified synthesis of prostaglandin analogs, and novel chemical compounds useful as intermediates in such synthesis.Prostaglandins (PGs) are organic carboxylic acids, namely cyclopentanes carrying two side chain substituents, typically linear C6-C8 side chains, bonded to adjacent positions on the cyclopentane nucleus. One of the side chains, the α-side chain, carries a terminal carboxylic acid group. Many are natural products found in mammalian organs and tissues (primary PGs), and exhibit a variety of physiological activities. Primary PGs generally have a prostanoic acid skeleton, which forms the basis of the nomenclature:A significant number of synthetic PG analogs have been made and found to have useful pharmacological properties. These may have modified skeletons, and substituted and unsaturated side chains. PGs are characterized by a hydroxyl (or ketone) substituent on the cyclopentane nucleus, position 9.Prostaglandin analogs are difficult to synthesize. Complications arise because of the requirements of the end products to have several functional groups and two side chains of significant size and complexity. Stereospecificity is commonly required, for substituent groups and for bonds in the core. Since the products are intended for pharmaceutical use, the range of industrially acceptable reagents, solvents, catalysts, etc. which can be used in their synthesis is limited to those having pharmaceutical industry acceptability.A common starting material for PG analog ...

About 1 percent of Americans have this illness.People with the disorder may hear voices other people don't hear. They may believe other people are reading their minds, controlling their thoughts, or plotting to harm them. This can terrify people with the illness and make them withdrawn or extremely agitated.People with schizophrenia may not make sense when they talk. They may sit for hours without moving or talking. Sometimes people with schizophrenia seem perfectly fine until they talk about what they are really thinking.Families and society are affected by schizophrenia too. Many people with schizophrenia have difficulty holding a job or caring for themselves, so they rely on others for help. Treatment helps relieve many symptoms of ...

The synthesis and in vitro and in vivo anti-breast and anti-prostate cancers activities of novel C-4 heteroaryl 13-cis retinamides that modulate Mnk-eIF4E and AR signaling are discussed. In both breast and prostate cancer cell lines, these compounds induce Mnk1/2 degradation to substantially suppress eIF4E phosphorylation. In prostate cancer cells, the compounds induce degradation of both full-length androgen receptor (fAR) and splice variant AR (AR-V7) to inhibit AR transcriptional activity. The consequences of these multiple activities resulted in inhibition of cell growth and migration and induction of apoptosis. Finally and importantly, the compounds demonstrate strong in vitro and in vivo anti-breast and anti-prostate cancer activities, with no apparent host toxicities. 2.

(canceled) The subject application claims benefit under 35 USC § 119(e) of U.S. provisional Application No. 62/018,008, filed Jun. 27, 2014. The entire contents of the above-referenced patent application are hereby expressly incorporated herein by reference.This invention relates to compositions, methods and kits for determining the presence and/or amount of vitamin D analytes, including vitamin D isomers, and metabolites thereof in a sample suspected of containing the same.The term “vitamin D” refers to a group of fat-soluble secosteroids. In humans, vitamin D is unique because it can be ingested as cholecalciferol (vitamin D) or ergocalciferol (vitamin D) and because the body can also synthesize it (from cholesterol) when sun exposure is adequate. Because of this latter property, vitamin D is considered by some to be a non-essential dietary vitamin although most consider it an essential nutrient. Vitamin D has an important physiological role in the positive regulation of calcium ion homeostasis. Vitamin Dis the form of the vitamin synthesized by animals. It is also a common supplement added to milk products and certain food products as is vitamin D.Both dietary and intrinsically synthesized vitamin Dmust undergo metabolic activation to generate bioactive metabolites. In humans, the initial step of vitamin Dactivation occurs primarily in the liver and involves hydroxylation to form the intermediate metabolite 25-hydroxycholecalciferol. Calcidiol is the major form of Vitamin Din the circulatory system. Vitamin Dalso undergoes similar metabolic activation to 25-hydroxyvitamin D. Collectively these compounds are called 25-hydroxyvitamin D (abbreviated 25(OH)D) and they are the major metabolites that are measured in serum to determine vitamin D status; 25(OH)D and its epimers are both pre-hormones that need to be converted into 1,25(OH)D to exert ...

Автор: Alan K. Richards

Improved initiators, solvents, and SO3 mixtures are disclosed herein, which can increase the yields and efficiency of a chemical manufacturing process which uses a radical chain reaction to convert methane (CH4), which is a gas under any normal conditions, into methane-sulfonic acid (MSA), a liquid. MSA is useful and valuable in its own right, and it also can be processed to create desulfured fuels and other valuable chemicals. A preferred initiator combination has been identified, comprising at least two different sulfate peroxide compounds. One type or class of initiator can be called a “primary” (or major, main, principle, dominant, or similar terms) initiator, and the other type or class of initiator can be can be regarded as an “extender” (or secondary, supplemental, enhancing, tuning, tweaking, or similar terms) initiator. “Primary” initiator(s) include (unmethylated) Marshall's acid, mono-methyl-Marshall's acid, and di-methyl-Marshall's acid, while a secondary/extender initiator comprises methyl-Caro's acid, which can oxidize sulfur DI-oxide (an unwanted chain terminator) into sulfur TRI-oxide (an essential reagent). Various other enhancements to the MSA manufacturing process also are described.
