Chemical structure cisplatin structure. Cisplatin is a chemotherapy medication used to treat a number of cancers. Cisplatin is the square planar coordination complex cis-Pt NH 3 2 Cl 2. 689 The prefix cis indicates the cis isomer in which two similar ligands are in adjacent positions.
550 The systematic chemical name of this molecule is cisdiamminedichloroplatinum. 286 where ammine with. Cisplatin has a molecular weight of 3011 gmmol a density of 374 gcm 3 a melting point of 270 C a log K ow of -219 and a water solubility of 253 gL at 25 C HSDB 2009.
Cisplatin was first synthesized by M. Peyrone in 1844 and its chemical structure was first elucidated by Alfred Werner in. Due to its unique chemical structure the chlorine atoms of cisplatin are more subject to chemical displacement reactions by nucleophiles such as water or sulfhydryl groups than to enzyme- catalyzed metabolism.
At physiological pH in the presence of 01M NaCl the predominant molecular species are cisplatin and monohydroxymonochloro. Cis-diammine platinum II in nearly equal concentrations. Structure of cisplatin an example of a molecule with the square planar coordination geometry.
The square planar molecular geometry in chemistry describes the stereochemistry spatial arrangement of atoms that is adopted by certain chemical compounds. As the name suggests molecules of this geometry have their atoms positioned at the corners. Numerous compounds adopt this.
ChemComm or Chemical Communications formerly known as Journal of the Chemical Society D. Chemical Communications 1969971 Journal of the Chemical Society Chemical Communications 1972995 is a peer-reviewed scientific journal published by the Royal Society of Chemistry. It covers all aspects of chemistry.
In January 2012 the journal moved to publishing 100 issues per year. The tertiary structure of a nucleic acid refers to the threedimensional arrangement of the nucleic acidthat is the arrangement of the molecule in space as in the tertiary structure of tRNA. Sugar structures in DNA and RNA Although RNA and DNA are similar in their overall properties the presence of the 2hydroxyl group of ribose in RNA and its replacement by 2deoxyribose in.
In its solid form it is a crystalline solid which has a tendency to readily lose water. Sodium thiosulfate is readily soluble in water and is also referred to as sodium hyposulfite. The structure of the Na 2 S 2 O 3 molecule is illustrated below.
This chemical reaction creates aluminum- or magnesium-bound phosphate salts that are non-absorbable by the body. Increased excretion of phosphate occurs primarily in the renal system. The proximal renal tubule reabsorbs up to 70 of filtered phosphate normally and the distal tubule reabsorbs up to 15 of filtered phosphate.
Resorption is regulated by serum phosphate concentration with mild. Nabilone marketed as Cesamet is a synthetic form of delta-9-tetrahydrocannabinol Δ⁹-THC the primary psychoactive component of cannabis marijuana. Although structurally distinct from THC nabilone mimics THCs structure and pharmacological activity through weak partial agonist activity at Cannabinoid-1 CB1R and Cannabinoid-2 CB2R receptors however it is considered to be twice as.
Gemcitabine is a cytosine analogue and intravenously administered antineoplastic agent used in the therapy of several forms of advanced pancreatic lung breast ovarian and bladder cancer. Gemcitabine is associated with a high rate of transient serum enzyme elevations during therapy but is a very rare cause of acute clinically apparent liver injury. Thus there has been a concerted effort to develop improved analytical separation and structure-specific lipid characterization methods including novel chemical derivatization chromatographic electrophoretic and ion mobility separations in situ ionization imaging and tandem mass spectrometry MSMS and multistage MSMS ie MSn techniques employing ozone photochemical derivatization.
The Journal of the American Chemical Society JACS founded in 1879 is the flagship journal of the American Chemical Society and the worlds preeminent journal in all of chemistry and interfacing areas of science.

Similarly cisplatin is an effective anticancer drug whereas its isomer transplatin exhibits no anti-cancer benefits at all. One of the most famous examples is that of thalidomide pictured below. While one isomer of thalidomide is a potent morning sickness suppressant it was delivered at a 5050 ratio with its stereoisomer which was responsible for the.
