<p>Glycopyrrolate related B is a drug product that belongs to the class of drugs for research and development. It is a natural metabolite of glycopyrrolate and is used as an analytical standard. The metabolite can also be used as a synthetic intermediate or impurity standard in pharmaceutical production. It has been shown that glycopyrrolate related B has niche applications in drug development and metabolism studies. Glycopyrrolate related B is not found in the pharmacopeia, but it can be synthesized by reacting the corresponding amine with pyrrole-2-carboxaldehyde.</p>

<p>PSI 7976 is an analog of the nucleophilic attack drug, ribavirin. PSI 7976 inhibits the hepatitis C virus (HCV) replicon by inhibiting the function of the NS5B polymerase. In clinical studies, PSI 7976 has been shown to be active against HCV genotype 1 and 3. It has also been shown to inhibit replication of HIV-1 in vitro and to act synergistically with lamivudine against HIV-1 in human cells. PSI 7976 may be useful as a potential antiviral agent for treatment of other viral infections such as hepatitis B virus (HBV), herpes simplex virus type 2 (HSV-2), or cytomegalovirus (CMV).</p>

<p>Simvastatin is a statin that reduces cholesterol synthesis by inhibiting the enzyme HMG-CoA reductase. Simvastatin is an amide, which is a derivative of the drug substance with a chloride group. It is commonly used in pharmaceutical formulations as an impurity in the synthesis of simvastatin. The presence of this impurity can be detected using chromatographic techniques, such as liquid chromatography and gas chromatography.</p>

<p>Gentamicin Impurity</p>

<p>N-[4-Cyano-3-(trifluoromethyl)phenyl]-2-methyloxirane-2-carboxamide (NUOX) is a potential anticancer agent that has been shown to have an acidic pKa of 5.8 and to be active against cancer cells in the same way as bicalutamide, which is a known antiandrogen. NUOX has been shown to increase the number of cavities in polybenzimidazole (PBI) films by enhancing the rate of oxidation. NUOX also inhibits the growth of human cancer cells by binding sulfide groups on proteins and DNA, inhibiting cellular respiration. NUOX is not water soluble, so it must be dissolved in solvents such as acetonitrile or chloroform before administration.</p>

<p>N-Hydroxymethyl Sumatriptan is an analytical standard and a research and development impurity. It is also used as an API impurity in drug product manufacturing. N-Hydroxymethyl Sumatriptan can be synthesized by reacting the parent drug with hydroxyl radicals, which is a process that yields no side products. N-Hydroxymethyl Sumatriptan can be found in the following pharmacopoeia: United States Pharmacopoeia (USP) 11&gt;, European Pharmacopoeia (EP), Japanese Pharmacopoeia (JP)13&gt;, British Pharmacopoeia (BP), and Chinese Pharmacopiae (CPC).</p>
