50 to 100 mg/mL at 74.3° F (NTP, 1992) GENERALLY INSOL IN ORGANIC SOLVENTS, BUT SLIGHTLY SOL IN ETHANOL & CELLOSOLVE Solubility in water = 80 mg/ml, in ethanol = 3 mg/ml, in methyl Cellosolve(monomethyl ether of ethylene glycol) = 40 mg/ml.
Orange G is synthesized by coupling diazonium salt of sulfanilic acid with Naphthol AS. The reaction takes place in an alkaline medium, and the product is obtained as an orange powder. The yield of the reaction is around 80%, and the efficiency of the process is high. However, the synthesis of Orange G involves the use of toxic chemicals, such as sodium nitrite and hydrochloric acid, which can pose environmental and safety hazards.
Chemical Structure and Biological Activity
The chemical structure of Orange G consists of two aromatic rings linked by an azo group (-N=N-). The dye has a molecular weight of 452.4 g/mol and a melting point of 300°C. Orange G is a water-soluble dye that absorbs light in the visible region, with a maximum absorption at 480 nm. The biological activity of Orange G is attributed to its ability to bind to proteins and nucleic acids. It is commonly used as a biological stain for protein electrophoresis and as a marker for DNA sequencing.
Orange G has been shown to affect cell function and signal transduction. It can induce oxidative stress and DNA damage in cells, leading to cell death. Orange G has also been shown to have potential therapeutic effects, such as anti-inflammatory and anti-cancer properties. However, Orange G can also have toxic effects, such as mutagenicity and carcinogenicity, which can pose health risks to humans and animals.
In medical research, Orange G is used as a biological stain for protein electrophoresis and as a marker for DNA sequencing. It has also been studied for its potential therapeutic effects, such as anti-inflammatory and anti-cancer properties. In environmental research, Orange G is used to study the effects of pollutants on ecosystems and to monitor pollution levels in water bodies. In industrial research, Orange G is used in manufacturing processes, such as dyeing textiles and paper, and improving product quality and efficiency. However, the use of Orange G in these applications can pose health and safety considerations.

CP 481715 a potent and selective CCR1 antagonist with potential therapeutic implications for inflammatory diseases. P-481,715 binds to human CCR1 with a Kd of 9.2 nm. and displaces 125I-labeled CCL3 from CCR1-transfected cells with an IC50 of 74 nm. CP-481,715 fully blocks the ability of CCL3 and CCL5 to stimulate receptor signaling (guanosine 5'-O-(thiotriphosphate) incorporation; IC50 = 210 nm), calcium mobilization (IC50 = 71 nm), monocyte chemotaxis (IC50 = 55 nm), and matrix metalloproteinase 9 release (IC50 = 54 nm). CP-481,715 retains activity in human whole blood, inhibiting CCL3-induced CD11b up-regulation and actin polymerization (IC50 = 165 and 57 nm, respectively) on monocytes. CP-481,715 inhibits cell infiltration and inflammatory responses in human CCR1 transgenic mice.
