Synthetic cannabinoids are becoming increasingly popular as substances of abuse. However, in the Netherlands synthetic cannabinoid intoxications are rare. We report a 16-year-old male who became deeply comatose and was admitted to the intensive care unit for invasive mechanical ventilation after a buse of aninitially unknown drug. Routine toxicology screening with an immunoassay only detected t...

Methadone (adolphine, dolophine, adanon, amidone, physeptone, althose, miadon, butalgin, diadone, polimadone) is a synthetic substitute for heroin. The drug was originally synthesized by the German firm I. G. Farben in 1941 and appropriately named "Adolphine." Since morphine was unavailable in Germany during World War II for relieving pain in battlefield injuries, methadone was developed as a s...

The CDH1 gene, which encodes the cell-to-cell adhesion protein E-cadherin, is frequently mutated in lobular breast cancer (LBC) and diffuse gastric cancer (DGC). However, because E-cadherin is a tumor suppressor protein and lost from the cancer cell, it is not a conventional drug target. To overcome this, we have taken a synthetic lethal approach to determine whether the loss of E-cadherin crea...

In pharmaceutical formulations, phospholipids obtained from plant or animal sources and synthetic phospholipids are used. Natural phospholipids are purified from, e.g., soybeans or egg yolk using non-toxic solvent extraction and chromatographic procedures with low consumption of energy and minimum possible waste. Because of the use of validated purification procedures and sourcing of raw materi...

A new, rapid, economical and isocratic reverse phase high performance liquid chromatography (RP-HPLC) method was developed for the determination of eptifibatide acetate, a small synthetic antiplatelet peptide, in bulk drug substance and pharmaceutical dosage forms. The developed method was validated as per of ICH guidelines. The chromatographic separation was achieved isocratically on C18 colum...

Poly(lactic-co-glycolic) acid (PLGA) has attracted a considerable amount of interest for biomedical application due to its biocompatibility, tailored biodegradation rate (depending on the molecular weight and copolymer ratio), approval for clinical use in humans by the U.S. Food and Drug Administration (FDA), the potential to change surface properties to create better interaction with biologica...

Synthetic lethality is a rational approach to identify candidate drug targets for selective killing of cancer cells harboring somatic mutations that cause chromosome instability (CIN). To identify a set of the most highly connected synthetic lethal partner genes in yeast for subsequent testing in mammalian cells, we used the entire set of 692 yeast CIN genes to query the genome-wide synthetic l...

Synthetic cathinones represent one of the main groups new psychoactive substances. The variety and rapid distribution synthetic on drug market can be explained by an easy modification their structure insufficient legislation. This fact requires development selective effective analytical methods for monitoring cathinone in biological samples. report summarizes current knowledge concerning identi...

IM A G E : LA G U N A D E S IG N /G E TT Y IM A G E S The United States Pharmacopeial Convention (USP) Therapeutic Peptides Expert Panel was formed in 2013 to evaluate quality attributes for synthetic peptides based on currently available regulatory guidance and expectations. Public quality standards for drug products and drug substances are developed by USP and enforceable by FDA. This series ...
