Alarelin acetate is a gondatrophin releasing hormone. Natural forms of alarelin found in animals are used to induce ovulation. Synthetic versions of this product are created using an LH-RH antagonist which is commonly set in larger doses than the natural LH-RH that is typically found in the rat hypophyseal stimulation or the gondatoropin secretions in induced ovulation or in vitro.
 
This chemical is the acetate form of the natural hypothalamic peptide which is used by an animal’s body to release LH and FSH from the pituitary gland. The peptide alarelin acetate has a single non-glycosylated polypeptide structure that is made up of nine amino acids. This has a molecular mass of 1167.3.
 
Alarelin is commonly used in research settings both to better understand this peptide’s effects on an animal’s body and to induce conditions that may assist with reproductive research. Samples of this chemical intended for research settings are typically stable for around three weeks at room temperature, and will need to be stored at temperatures below -18 degrees Celsius for long term use.
 
Most versions of this chemical are shipped as a lyophilized powder that can be reconstituted at a sterile temperature. This chemical may remain stable for up to three weeks at room temperature if it is kept sealed when it is not in use. If this product will be used for long periods of time is should be kept in a freezer with a waterproof sea.
 
If the mixture has already been reconstituted it can be kept at 40 degrees Celsius for 2-7 days but should be kept at -180 degrees Celsius for longer periods of time. Do not continually refreeze and thaw the product.

Chitosan Description:
 
Chitosan is a linear polysaccharide composed of randomly distributed β-(1-4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). It is made by treating shrimp and other crustacean shells with the alkali sodium hydroxide.
 
Chitosan has a number of commercial and possible biomedical uses. It can be used in agriculture as a seed treatment and biopesticide, helping plants to fight off fungal infections. In winemaking it can be used as a fining agent, also helping to prevent spoilage. In industry, it can be used in a self-healing polyurethane paint coating. In medicine, it may be useful in bandages to reduce bleeding and as an antibacterial agent; it can also be used to help deliver drugs through the skin.
 
More controversially, chitosan has been asserted to have use in limiting fat absorption, which would make it useful for dieting, but there is evidence against this.
 
Other uses of chitosan that have been researched include use as a soluble dietary fiber.
 
Chitosan is extracted from chitin, insoluble in water but soluble in dilute acid and absorbed by human body. As the firdt derivate, it's chemical constitution is macromolecule alkalescent polysaccharide polymer with cation. It has peculiar physical, chemical properties and bioactive function.
 
Chitosan is listed as follows:
A. High Density Chitosan
B. High Viscosity Chitosan
C. Industrial Grade Chitosan
D. Food Grade Chitosan
E. Medical Grade Chitosan
F. Low Molecular Weight Chitosan
G. Aroxymethyl Chitosan
H. Chitosan Oligosaccharide

Chitosan is refined from deacetylation of chitin which is extracted from deep-sea Alaska crab cods. As the only basic polysaccharide among natural polysaccharides, this product has many physical and chemical characteristics and physiological activities. Precisely, this product can control cholesterol, inhibit bacterial activity, prevent and control high blood pressure, absorb and excrete heavy metals, maintain humidity and strengthen immunity. In food industry, this product can be used as antibacterial agent, fruit and vegetable preservative and antioxidant. There are many special functional groups in molecular chain, so the chitosan can be manufactured into many products according to different reactions on functional groups, such as acylation, sulfation and oxidation, grafting and crosslinking, hydroxyethylation and hydroxymethylation. These products can be used in many fields, including medicine, food, chemical, cosmetic, water treatment, metal extraction and recovery, biochemical and biomedical engineering. There are many types of chitosan, including GS-chitosan oligosaccharide, high density type, special molecular weight type, medical/food / industrial grade type, water soluble type and specialized type.
Chitosan can inhibit growth and reproduction of fungi, bacteria, and virus. When this product is used as coating preservation, it can inhibit respiratory metabolism and water loss of fruits and vegetables, thus slowing their aging process of organization and structure and effectively extending their postharvest life. This product can also be used as antioxidant. In heating process, free iron ions are released from meat hemoglobin and they form chelates with chitosan, thus their catalytic activity is inhibited.
 
Chitosan Usage:
 
Agricultural and horticultural use
The agricultural and horticultural uses for chitosan, primarily for plant defense and yield increase, are based on how this glucosamine polymer influences the biochemistry and molecular biology of the plant cell. The cellular targets are the plasma membrane and nuclear chromatin. Subsequent changes occur in cell membranes, chromatin, DNA, calcium, MAP Kinase, oxidative burst, reactive oxygen species, callose pathogenesis-related (PR) genes and phytoalexins.
 
Natural biocontrol and elicitor
In agriculture, chitosan is used primarily as a natural seed treatment and plant growth enhancer, and as an ecologically friendly biopesticide substance that boosts the innate ability of plants to defend themselves against fungal infections. The natural biocontrol active ingredients, chitin/chitosan, are found in the shells of crustaceans, such as lobsters, crabs, and shrimp, and many other organisms, including insects and fungi. It is one of the most abundant biodegradable materials in the world.

Pharmaceutical Grade Reducing Fat Mass Chemicals Sr9011 SR-9011 1379686-29-9
 
SR9011 Basic Info:
 
Product Name: SR9011
Synonyms: 3-(((4-chlorobenzyl)((5-nitrothiophen-2-yl)methyl)amino)methyl)-N-pentylpyrrolidine-1-carboxamide
CAS No: 1379686-29-9
Molucelar Formula: C23H31ClN4O3S
Molucelar Weight: 479.03524
Solubility: DMSO up to 100 mM
 
Sr9011 Description:
 
SR9011 is a trifunctional methacrylate monomer that provides exceptional adhesion to metal substrates.
SR9011 is recommended for use in peroxide cured coatings, sealants, and PVC-based plastisols. Usage levels of 5% to 10% by weight are recommended.
 
SR9011 is a potent and specific synthetic REV-ERB agonist that binds to REV ERB α with an EC50 ~790 nM and REV-ERB-β with EC50 ~560 nM. It also has good in vivo plasma/brain exposure. The nuclear receptors REV-ERB-α and REV-ERB-β play an integral role in regulating the expression of core clock proteins, driving rhythms in activity and metabolism. Administration of SR9011 alters circadian behavior and the circadian pattern of core clock gene expression in the hypothalami of mice. The circadian expression pattern of an array of metabolic genes in the liver, skeletal muscle and adipose tissue was also altered, resulting in increased energy expenditure. Treatment of diet induced obese mice with SR9011 decreased obesity by reducing fat mass and markedly improved dyslipidaemia and hyperglycaemia. These results indicate that synthetic REV-ERB ligands that pharmacologically target the circadian rhythm may be beneficial in the treatment of sleep disorders as well as metabolic diseases.
 
Sr9011 Application:
 
In vitro: SR9011 was used at 5-10 μM concentration in vitro and in cellular assays.
In vivo: IP administration of SR9011 was used at 100 mg/kg once or twice per day for 12-30 days in different mouse models.
