Basic Information of Fulvestrant

Chemical Name: Fulvestrant

Cas No.: 129453-61-8

Molecular Formula: C32H47F5O3S

Chemical Structure:

Fulvestrant, sold under the brand name Faslodex among others, is a medication used to treat hormone receptor (HR)-positive metastatic breast cancer in postmenopausal women with disease progression as well as HR-positive, HER2-negative advanced breast cancer in combination with palbociclib in women with disease progression after endocrine therapy. It is given by injection into a muscle.

Fulvestrant is a selective estrogen receptor degrader (SERD) and was first-in-class to be approved. It works by binding to the estrogen receptor and destabilizing it, causing the cell's normal protein degradation processes to destroy it.

Fulvestrant is used for the treatment of hormone receptor positive metastatic breast cancer or locally advanced unresectable disease in postmenopausal women; it is given by injection. A 2017 Cochrane review found it is as safe and effective as first line or second line endocrine therapy.

It is also used to treat HR-positive, HER2-negative advanced or metastatic breast cancer in combination with palbociclib in women with disease progression after first-line endocrine therapy.

Hormones are chemical substances that are produced by glands in the body, which enter the bloodstream and cause effects in other tissues. For example, the hormone testosterone made in the testicles and is responsible for male characteristics such as deepening voice and increased body hair. The use of hormone therapy to treat cancer is based on the observation that receptors for specific hormones that are needed for cell growth are on the surface of some tumor cells.  Hormone therapies work by stopping the production of a certain hormone, blocking hormone receptors, or substituting chemically similar agents for the active hormone, which cannot be used by the tumor cell.  The different types of hormone therapies are categorized by their function and/or the type of hormone that is affected.

Many breast cancers have estrogen receptors, and the growth of these tumors can be stimulated by estrogen. Fulvestrant is an estrogen receptor downregulator, this means it binds to the estrogen receptor site in competition with estrogen in the body.  Once it binds to the site it causes the receptors to break down, thereby preventing normal cellular response to estrogen.

Fulvestrant is a selective estrogen receptor degrader (SERD).

It works by binding to the estrogen receptor and making it more hydrophobic, which makes the receptor unstable and misfold, which in turn leads normal processes inside the cell to degrade it.

Fulvestrant is slowly absorbed and maximum plasma concentrations (Cmax) are reached after about 5 days and the terminal half-life is around 50 days. Fulvestrant is highly (99%) bound to plasma proteins including very low density lipoprotein, low density lipoprotein, and high density lipoprotein. It appears to be metabolized along the same pathways as endogenous steroids; CYP3A4 may be involved, but non-cytochrome routes appear to be more important. It does not inhibit any CYP450 enzymes. Elimination is almost all via feces.

Basic Information of Lead acetate trihydrate

Chemical Name: Lead acetate trihydrate

Cas No.: 6080-56-4

Molecular Formula: Pb(C2H3O2)2

Chemical Structure:

 

Lead(II) acetate (Pb(CH3COO)2), also known as lead acetate, lead diacetate, plumbous acetate, sugar of lead, lead sugar, salt of Saturn, or Goulard's powder, is a white crystalline chemical compound with a sweetish taste. It is made by treating lead(II) oxide with acetic acid. Like other lead compounds, it is toxic. Lead acetate is soluble in water and glycerin. With water it forms the trihydrate, Pb(CH3COO)2·3H2O, a colourless or white efflorescent monoclinic crystalline substance.

The substance is used as a reagent to make other lead compounds and as a fixative for some dyes. In low concentrations, it is the principal active ingredient in progressive types of hair colouring dyes. Lead(II) acetate is also used as a mordant in textile printing and dyeing, and as a drier in paints and varnishes. It was historically used as a sweetener and for cosmetics.

Like other lead(II) salts, lead(II) acetate has a sweet taste, which led to its historical use as a sugar substitute. The ancient Romans, who had few sweeteners besides honey, would boil must (grape juice) in lead pots to produce a reduced sugar syrup called defrutum, concentrated again into sapa. This syrup was used to sweeten wine and to sweeten and preserve fruit. It is possible that lead(II) acetate or other lead compounds leaching into the syrup might have caused lead poisoning in those who consumed it. Lead acetate is no longer used in the production of sweeteners because of its recognized toxicity. Modern chemistry can easily detect it, which has almost completely stopped the illegal use that continued decades after legal use as a sweetener was banned.

Lead(II) acetate paper is used to detect the poisonous gas hydrogen sulfide. The gas reacts with lead(II) acetate on the moistened test paper to form a grey precipitate of lead(II) sulfide.

An aqueous solution of lead(II) acetate is the byproduct of the 50/50 mixture of hydrogen peroxide and white vinegar used in the cleaning and maintenance of stainless steel firearm suppressors (silencers) and compensators. The solution is agitated by the bubbling action of the hydrogen peroxide, and the main reaction is the dissolution of lead deposits within the suppressor by the acetic acid, which forms lead acetate. Because of its high toxicity, this chemical solution must be appropriately disposed by a chemical processing facility or hazardous materials centre. Alternatively, the solution may be reacted with sulfuric acid to precipitate nearly insoluble lead(II) sulfate. The solid may then be removed by mechanical filtration and is safer to dispose of than aqueous lead acetate.

Basic Information of 1-Naphthalene acetic acid

Chemical Name: 1-Naphthalene acetic acid

Cas No.: 86-87-3

Molecular Formula: C12H10O2

Chemical Structure:

1-Naphthaleneacetic acid (NAA) is an organic compound with the formula C10H7CH2CO2H. This colorless solid is soluble in organic solvents. It features a carboxylmethyl group (CH2CO2H) linked to the "1-position" of naphthalene. NAA is a synthetic plant hormone in the auxin family and is an ingredient in many commercial plant rooting horticultural products; it is a rooting agent and used for the vegetative propagation of plants from stem and leaf cutting. It is also used for plant tissue culture.

The hormone NAA does not occur naturally, and, like all auxins, is toxic to plants at high concentrations. In the United States, under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), products containing NAA require registration with the Environmental Protection Agency (EPA) as pesticides.

NAA is widely used in agriculture for various purposes. It is considered to be only slightly toxic but when at higher concentrations it can be toxic to animals. This was shown when tested on rats via oral ingestion at 1000–5900 mg/kg. NAA has been shown to greatly increase cellulose fiber formation in plants when paired with another phytohormone called gibberellic acid. Because it is in the auxin family it has also been understood to prevent premature dropping and thinning of fruits from stems. It is applied after blossom fertilization. Increased amounts of it can actually have negative effects however, and cause growth inhibition to the development of plant crops. It has been used on many different crops including apples, olives, oranges, potatoes, and various other hanging fruits. In order for it to obtain its desired effects it must be applied in concentrations ranging from 20–100 µg/mL. NAA present in the environment undergoes oxidation reactions with hydroxyl radicals and sulphate radicals. Radical reactions of NAA was studied by using pulse radiolysis technique. Hydroxyl adduct radical was formed as the intermediate during the reaction of hydroxyl radical with NAA. The intermediate Naphtyl methyl radical was formed during the reaction of sulphate radical anion with NAA.

In micro propagation of various plants NAA is typically added to a media containing nutrients essential to the plants survival. It is added to help induce root formation in various plant types. It can also be applied by spraying it onto plants and which is typical in agricultural use. It is prohibited in many areas to use it in high concentrations due to the health concerns towards humans and other animals.

LEAPChem Highlights Cefixime today!

Basic Information of Cefixime

Chemical Name: Cefixime

Cas No.: 79350-37-1

Molecular Formula: C16H15N5O7S2

Chemical Structure:

Cefixime is an antibiotic useful to treat a number of bacterial infections. This includes otitis media, strep throat, pneumonia, urinary tract infections, gonorrhea, and Lyme disease. For gonorrhea typically only one dose is required. In the United States it is a second line treatment to ceftriaxone for gonorrhea. It is taken by mouth.

Common side effects include diarrhea, abdominal pain, and nausea. Serious side effects may include allergic reactions and Clostridium difficile diarrhea. It is not recommended in people with a history of a severe penicillin allergy. It appears to be relatively safe during pregnancy. It is in the third generation cephalosporin class of medications. It works by disrupting the bacteria's cell wall resulting in its death.

Cefixime is a semi-synthetic (partially man-made), oral antibiotic in the cephalosporin family of antibiotics. The cephalosporin family includes cephalexin (Keflex), cefaclor (Ceclor), cefuroxime (Zinacef), cefpodoxime (Vantin), cefprozil (Cefzil), and many injectable forms. Like other cephalosporins, cefixime stops bacteria from multiplying by preventing bacteria from forming the walls that surround them. The walls are necessary to protect bacteria from their environment and to keep the contents of the bacterial cell together; most bacteria cannot survive without a cell wall. Cefixime is active against a very wide spectrum of bacteria such as Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes (the cause of strep throat), Hemophilus influenzae, Moraxella catarrhalis, E. coli, Klebsiella, Proteus mirabilis, Salmonella, Shigella, and Neisseria gonorrhoeae. The FDA approved cefixime in April 1989.
