DNA-damaging agents are widely used in cancer treatment despite their lack of tumor specificity. Human NQO2 (quinone oxidoreductase-2) is an atypical oxidoreductase because no endogenous electron donor has been identified to date. The enzyme converts CB1954 [5-(aziridin-1-yl)-2,4-dinitrobenzamide],
This study was conducted to explore the effect of graded levels of pyrroloquinoline quinone disodium (PQQ·Na2) on the performance and intestinal development of weaned pigs. A total of 216 pigs weaned at 28 d were assigned in a randomized complete block design to 6 diets containing 0, 1.5, 3.0, 4.5,
Diaziquone (AZQ), a synthetic quinone with demonstrated activity against acute nonlymphocytic leukemia (ANLL), primary CNS tumors, and non-Hodgkin's lymphoma (NHL), is virtually devoid of nonhematopoietic toxicity at conventional doses. As a prelude to its inclusion into bone marrow transplant (BMT)
Aziridinylbenzoquinone (AZQ: NSC-182986), is a quinone derivative which has been shown to have activity in implanted murine tumor systems. Toxicity in small and large animals included hypothermia, diarrhea, anorexia, emesis, weight loss, and gastrointestinal bleeding. In addition, there was
A 51-year-old woman with a history of asthma and Hashimoto's thyroiditis presented to the dermatology service with a chief complaint of "itchy bumpy rashes" that persisted beyond 24 hours. She noted that, 3 days prior to the onset of urticaria, a pyrroloquinoline quinone supplement had been started.

The anaerobic parasite Giardia lamblia, causative agent of persistent diarrhea, contains a family of nitroreductase genes most likely acquired by lateral transfer from anaerobic bacteria or archaebacteria. Two of these nitroreductases, containing a ferredoxin domain at their N-terminus, NR1, and
BACKGROUND
Anthrone and oxanthrone are important anthraquinone derivatives present in medicinal plants which are used in therapeutics as laxatives. Some of these plants need to be stored at least one year before they can be used in order to oxidize anthrones into oxanthrones, so to avoid severe
Cisplatin, an antineoplastic drug, is widely used as a foremost therapy against numerous forms of cancer but it has pronounced adverse effects viz., nephrotoxicity, ototoxicity etc. CDDP-induced emesis and diarrhea are also marked toxicities that may be due to intestinal injury. Chrysin
Quinone derivatives have shown intensive antitumor activity in a broad variety of neoplasias. Aziridinylbenzoquinone is designed to have adequate lipid solubility to attain useful drug concentrations in the central nervous system. A Phase I study of aziridinylbenzoquinone was conducted in 32
Amrubicin is a synthetic 9-aminoanthracycline that has significant antitumor activity in Japanese patients with extensive stage small cell lung cancer (SCLC). Clinical trials ongoing in the United States and Europe will determine whether amrubicin will be effective in other ethnic groups (whites) or
