Dual effects of pyrazofurin and 3-deazauridine upon pyrimidine and purine biosynthesis in mouse L1210 leukemia. (2/16)

Pyrazofurin (NSC 143095) as the monophosphate derivative is a potent inhibitor of orotidine 5'-monophosphate (OMP) decarboxylase of the pyrimidine pathway and has been proposed to inhibit 5-aminoimidazole-4-carboxamide ribotide (AICAR) transformylase (EC 2.1.2.3) of the purine pathway (J. F. Worzalla, and M. J. Sweeney, Pyrazofurin inhibition of purine biosynthesis via 5-aminoimidazole-4-carboxamide-1-beta-D-ribofuranosyl 5'-monophosphate formyltransferase. Cancer Res., 40: 1482-1485, 1980). Measurement of levels of pyrimidine and purine intermediates in cultured mouse L1210 leukemia cells has shown that 25 microM pyrazofurin induces an 8-fold accumulation of OMP and large accumulations of intermediates proximal to the blockade with abrupt decreases in uridine and cytidine nucleotides. Considerable increases in the cellular concentrations of N-succino-AICAR (SAICAR), AICAR, 5-formamidoimidazole-4-carboxamide ribotide (FAICAR), IMP, XMP, and GMP at later times indicate that AICAR transformylase is not significantly inhibited in cultured cells; rather the purine pathway and the GMP branch are stimulated. However, addition of 25 microM 3-deazauridine (NSC 126849) to leukemia cells did result in inhibition of AICAR transformylase: AICAR and SAICAR accumulated, IMP disappeared and there was a large accumulation of guanosine nucleotides. Blockade of pyrimidine biosynthesis by derivatives of pyrazofurin or 3-deazauridine spares 5-phosphoribosyl-1-pyrophosphate and L-glutamine, elevated concentrations of which may stimulate initial reactions of purine biosynthesis and the reaction XMP----GMP.  (+info)

Formation of 1-beta-D-arabinofuranosylcytosine diphosphate choline in cultured human leukemic RPMI 6410 cells. (3/16)

When incubated with 1-beta-D-arabinofuranosylcytosine (ara-C), RPMI 6410 cells formed a hitherto unrecognized ara-C metabolite, 1-beta-D-arabinofuranosylcytosine diphosphate choline. This compound was characterized by (a) chromatographic behavior, (b) chemical and enzymatic hydrolysis, (c) phosphorus content, and (d) incorporation of [5-3H]ara-C and [methyl-14C]choline. Formation of 1-beta-D-arabinofuranosylcytosine diphosphate choline by RPMI 6410 cells was enhanced in the presence of 3-deazauridine (DU) and was preceded by that of 1-beta-D-arabinofuranosylcytosine triphosphate. The antiproliferative effects of ara-C and DU toward RPMI 6410 cells were potentiated when the agents were present together. The anabolism of ara-C during a 24-hr interval of culture was markedly enhanced by the presence of DU; cellular concentrations of 1-beta-D-arabinofuranosylcytosine triphosphate and 1-beta-D-arabinofuranosylcytosine diphosphate choline were 5- and 15-fold higher than those in the absence of DU. This enhancement appears to be the basis of the potentiation of cytotoxicity resulting from combination of the agents. Pretreatment of RPMI 6410 cells with DU resulted in enhanced rates of cellular uptake of ara-C. ara-C uptake under these circumstances was blocked by the inhibitor of nucleoside transport, nitrobenzylthioinosine.  (+info)

Formation of 1-beta-D-arabinofuranosylcytosine diphosphate choline in neoplastic and normal cells. (4/16)

1-beta-D-Arabinofuranosylcytosine diphosphate choline was formed from 1-beta-D-arabinofuranosylcytosine (ara-C) during incubation in vitro of peripheral myeloblasts from patients with acute myelogenous leukemia and cultured cells (nonleukemic human lymphocytes, mouse lymphoma L5178Y, and HeLa); as well, 1-beta-D-arabinofuranosylcytosine diphosphate choline was formed in vivo in mouse leukemia L1210 cells and mouse liver. 3-Deazauridine enhanced the anabolism of ara-C in nonleukemic lymphocytes in vitro and leukemia L1210 cells in vivo but did not influence ara-C anabolism in the other cell types. In acute myelogenous leukemia myeloblasts incubated in vitro with ara-C, concentrations of 1-beta-D-arabinofuranosylcytosine 5'-triphosphate were maximal after 8 hr of incubation and formation of the latter preceded that of 1-beta-D-arabinofuranosylcytosine diphosphate choline.  (+info)

Effects of pyrimidine antagonists on sialic acid regeneration in HL-60 cells. (5/16)

Because alterations in cell membrane sialoglycoconjugates can affect the behavior of neoplastic cells, we investigated the effects of in vitro treatment with antimetabolites used in cancer therapy on the expression of membrane sialic acid in cultured HL-60 leukemic cells. In these studies, cells were incubated with Vibrio cholerae neuraminidase to remove surface sialic acid. Reappearance of membrane sialic acid during drug treatment was followed (a) by measuring changes in radioactive surface labeling of viable cells with sodium metaperiodate-sodium[3H]-borohydride, (b) by measuring the decline in accessible surface galactosyl receptor sites which occurred coincident with membrane sialic acid replacement, and (c) by measuring the incorporation of [3H]glucosamine into membrane-associated neuraminidase-labile sialic acid. We were especially interested in learning whether drugs that affect intracellular pools of cytidine triphosphate (CTP), an important nucleotide intermediate in sialylation reactions, could inhibit regeneration of membrane sialic acid. 3-Deazauridine, a competitive inhibitor of CTP synthetase, depleted CTP pools and curtailed surface membrane resialylation with little or no effect on synthesis of de novo sialic acid from precursor sugars. The addition of cytidine restored CTP pools and sialic acid regeneration. Acivicin, a glutamine antagonist, also depleted CTP pools and curtailed surface membrane resialylation. In addition, it retarded de novo synthesis of sialic acid. The addition of cytidine restored intracellular CTP pools and sialic acid regeneration. However, both cytidine and guanosine were required to restore sialic acid synthesis from precursor sugars. 1-beta-D-Arabinofuranosylcytosine, a competitive inhibitor of sialic acid synthetase and of sialyltransferase, inhibited both de novo sialic acid synthesis and membrane resialylation. Only the latter effect was reversed by the addition of exogenous cytidine. Hydroxyurea, an agent shown previously to inhibit glycoconjugate production in hamster fibroblasts, curtailed membrane resialylation and de novo synthesis of sialic acid without depleting CTP pools. Doxorubicin, at levels that caused marked arrest of cell proliferation, had no effect on sialic acid synthesis or expression on the membrane surface. These data suggest that antimetabolites, apart from their cytotoxic effects or effects on cellular growth, may directly inhibit the expression of membrane sialic acid.(ABSTRACT TRUNCATED AT 400 WORDS)  (+info)

Drug sequence-dependent toxicity and small bowel mucosal injury in mice treated with low doses of 3-deazauridine and 1-beta-D-arabinofuranosylcytosine. (6/16)

The toxicity to mice of combinations of 1-beta-D-arabinofuranosylcytosine and 3-deazauridine was investigated. The drugs were administered daily i.p. on Days 1 to 5, each drug at 10 mg/kg body weight; these dosages are small fractions of the dosages at which 10% of the treated animals died when either drug was administered alone on the foregoing schedule. This drug combination was severely toxic when 3-deazauridine was administered 2 to 8 hr prior to 1-beta-D-arabinofuranosylcytosine; most mice treated in this way died within 3 days of the last treatment. Histological examination showed that severe damage to the small bowel mucosa resulted from treatment with the drugs in the above, lethal sequence. In contrast, treatments with this drug combination at the same dosages were tolerated when the two agents were administered simultaneously or when 1-beta-D-arabinofuranosylcytosine preceded 3-deazauridine. Under the latter conditions, small bowel mucosal injury was much less severe. Female mice were more sensitive to the toxic treatment regimen than were male mice and were protected against the latter when either the 3-deazauridine or the 1-beta-D-arabinofuranosylcytosine component was preceded by treatment with nitrobenzylthioinosine (100 mg/kg), a potent inhibitor of nucleoside transport.  (+info)

Synergistic action of 5-aza-2'-deoxycytidine and 3-deazauridine on L1210 leukemic cells and EMT6 tumor cells. (7/16)

The biochemical and biological effects of the combination of 5-aza-2'-deoxycytidine (5-aza-dCyd) and 3-deazauridine (3-DU) on L1210 leukemic cells and EMT6 tumor cells were investigated. The cytotoxic action of 5-aza-dCyd and 3-DU on both L1210 and EMT6 cells in vitro was synergistic when these agents were used in combination. The combination of 5-aza-dCyd and 3-DU produced a greater inhibition of in vitro growth of L1210 and EMT6 cells than did either agent alone. The in vivo antineoplastic activity of this combination was synergistic with respect to the increased survival time of BALB/c x DBA/2 F1 mice with L1210 leukemia. 3-DU, an agent that reduces the intracellular pool size of cytosine nucleotides, stimulated the incorporation of [3H]-5-aza-dCyd into DNA of both L1210 and EMT6 cells, suggesting that the synergistic action of this combination is related to the increased incorporation of 5-aza-dCyd in the presence of 3-DU.  (+info)

Penetration of 3-deazauridine into human brain, intracerebral tumor, and cerebrospinal fluid. (8/16)

The antitumor agent 3-deazauridine (DAU) was administered rapidly to four patients before surgical removal of intracerebral tumor. Tumor, adjacent brain tissue, and temporalis muscle were assayed for DAU by high-pressure liquid chromatography. DAU penetrated comparably into tumor, brain, and muscle; in one patient, tissue concentrations were higher than concurrent plasma concentrations. The active metabolite 3-deazauridine 5'-triphosphate was quantitated in one tumor sample and greatly exceeded its Ki for cytidine 5'-triphosphate synthetase. DAU was also present in autopsy brain specimens from two patients treated shortly antemortem. Cerebrospinal fluid concentrations were 22.1 and 59.0%, respectively, of concurrent plasma concentrations during continuous infusion of DAU in two patients. Cerebrospinal fluid concentration was 3.1 microgram/ml 2 hr after a 30-min infusion of 1.5 g of drug per sq m and fell to 1.9 microgram/ml at 16 hr. Thus, DAU is capable of penetrating into intracerebral tumor, brain, and cerebrospinal fluid and is worthy of investigation in the treatment of intracerebral and meningeal neoplasms.  (+info)

Starvation and antimetabolic therapy promote cytokine release and recruitment of immune cells | PNASStarvation and antimetabolic therapy promote cytokine release and recruitment of immune cells | PNAS
Nutrient limitation occurs during physiological tissue growth or as a consequence of various pathological events, such as wounds or vascular occlusions that lead to transient ischemia. To recover, ischemic tissues employ mechanisms that promote wound healing and the restoration of the nutrient flux. These mechanisms include angiogenesis and inflammation, which have been classically attributed to hypoxia or to necrotic inflammatory signals, respectively. We show here that nutrient deprivation could be, by itself, a powerful signal to induce inflammation as part of a normal wound-healing response as pathogens and sterile injuries trigger similar events which include the recruitment of the innate immune system. It is possible that nutrient deprivation followed by the ISR is one of the many signals that the body uses to detect infections as pathogens also deprive nutrients from the site of infection. In fact, the kinase PKR, that detects viral dsRNA, is one of the kinases that activate the ISR ...

This rule sets national emission standards for hazardous air pollutants (NESHAP) for hydrochloric acid (HCI) process steel pickling facilities and hydrochloric acid regeneration plants pursuant to section 112 of the Clean Air Act (Act).. Pickling is a process in which an acid solution is used to remove oxide scale from steel strip, rod, wire, tubing, and discreet shapes. Oxide scale forms on the surface of the steel when steel cools from a molten state. The steel pickling facilities that are affected by this rule use a solution of hydrochloric acid (HCl) to remove the oxide scale.. This process emits HCI, a hazardous air pollutant (HAP). Chronic exposure to HCl has been reported to cause gastritis, chronic bronchitis, dermatitis, and photosensitization. Acute inhalation exposure to HCl may cause hoarseness, inflammation and ulceration of the respiratory tract, chest pain, and pulmonary edema. Hydrochloric acid regeneration plants also emit chlorine (Cl2), which is also a HAP. Acute exposure to ...

During the seventies and eighties Peptichemio, a cocktail of six alkylating oligopeptides carrying m-L-sarcolysin, was investigated in a wide variety of human malignancies. Positive clinical results were suggested to result from rapid and effective DNA-crosslinking following uptake in neoplastic cells, but also from antimetabolic properties of the drug. Although m-L-sarcolysin never reached widespread clinical use, the well established para-isomer melphalan still, after nearly fifty years, has a place in cancer chemotherapy.. The present study was undertaken to synthesise the melphalan containing analogue of the tripeptide P2 (L-prolyl-m-L-sarcolysyl-p-L-fluorophenylalanine ethyl ester, the main contributor to Peptichemios activity) and similar compounds, preferably dipeptides. The new compounds compared favourably with melphalan, m-L-sarcolysin ...

Senescence Effects of Angelica sinensis Polysaccharides on Human Acute Myelogenous Leukemia Stem and Progenitor Cells Angelica sinensis polysaccharide;leukemia stem/progenitor cells;senescence;telomerase;telomere; Leukemia stem cells (LSCs) play important roles in leukemia initiation, progression and relapse, and thus represent a critical target for therapeutic intervention. Hence, it is extremely urgent to explore new therapeutic strategies directly targeting LSCs for acute myelogenous leukemia (AML) therapy. We show here that Angelica sinensis polysaccharide (ASP), a major active component in Dong quai (Chinese Angelica sinensis), effectively inhibited human AML $CD34^+CD38^-$ cell proliferation in vitro culture in a dose-dependent manner while sparing normal hematopoietic stem and progenitor cells at physiologically achievable concentrations. Furthermore, ASP exerted cytotoxic effects on AML K562 cells, especially LSC-enriched $CD34^+CD38^-$ cells. Colony formation assays further showed that ASP

Fluoride Action Network | New Way To Prepare Fluorinated PharmaceuticalsFluoride Action Network | New Way To Prepare Fluorinated Pharmaceuticals
A team of MIT chemists has devised a new way to add fluorine to a variety of compounds used in many drugs and agricultural chemicals, an advance that could offer more flexibility and potential cost-savings in designing new drugs.. Drug developers commonly add fluorine atoms to drugs, such as the cholesterol-lowering rosuvastatin, to keep the body from breaking them down too quickly. Many of these drugs contain aromatic rings - a type of six-carbon ring - and attaching a fluorine atom to the rings can be a difficult, expensive process.. Its hard to add fluorine at a late stage, once you have a complete molecule already put together, because traditional methods can be quite harsh with respect to temperature or other factors, says Stephen L. Buchwald, the Camille Dreyfus Professor of Chemistry at MIT.. In their new technique, Buchwald and his colleagues used a palladium catalyst to attach a fluorine atom to aromatic compounds. The technique could be used in the design and testing of new drugs, ...

Recently much attention has been devoted to crystals containing organic ions and inorganic ions due to the possibility of tuning their special structural features and their potential ferroelectrics properties (Fu et al., 2011; Zhang et al., 2010.).. The compound (C4H12O3N)+(C2F3O2)- has an asymmetric unit that consists of one tris(hydroxymethyl)methanaminium cation and one trifluoroacetate anion (Fig 1). N-H···O and O-H···O hydrogen bonds form a complex three-dimensional network, (Fig 2). The trifluoromethyl group is quite mobile, but examination of a difference map in the plane of the fluorine atoms does show that the fluorine atoms exist as three distinct atoms.. For structure of the related tris(hydroxymethyl)methanaminium hydrogenhalides seen (Rudman et al., 1983).. ...

2-Fluoroamphetamine (2-FA) is a stimulant drug from the amphetamine family which has been sold as a designer drug.[1] 2-Fluoroamphetamine differs from 3- and 4-fluoroamphetamine in the position of the fluorine atom on the aromatic ring, making them positional isomers of one another. The replacement of a hydrogen atom with a fluorine atom in certain compounds to facilitate passage through the blood-brain barrier, as is desirable in central nervous system pharmaceutical agents, is a common practice due to the corresponding increase in lipophilicity granted by the substitute.[2][3] ...

The bonding within dioxygen difluoride has been the subject of considerable speculation over the years, particularly because of the very short O-O distance and the long O-F distances. Bridgeman has proposed a scheme which essentially has an O-O triple bond and an O-F single bond that is destabilised and lengthened by repulsion between the lone pairs on the fluorine atoms and the π-orbitals of the O-O bond.[3] Repulsion involving the fluorine lone pairs is also responsible for the long and weak covalent bonding in the fluorine molecule.. ...

Results of the present study show for the first time that Chk1 undergoes activating phosphorylation in marrow blasts in vivo during cytarabine-containing induction therapy. Building on this result, we also show in human AML cell lines that the selective Chk1 inhibitor SCH 900776 abrogates cytarabine-induced S-phase arrest, increases cytarabine-induced apoptosis, and enhances the effects of cytarabine on colony formation. Likewise, SCH 900776 increases the effects of cytarabine in a majority of primary AML isolates but not normal myeloid progenitors in vitro. This sensitization was observed at SCH 900776 concentrations far below the approximate 5 μmol/L SCH 900776 peak levels observed at the maximum tolerated dose in solid tumor patients. These observations have potentially important implications for current efforts to enhance the efficacy of cytarabine-containing AML regimens.. Previous results have shown that cytarabine activates the ATR/Chk1 checkpoint in tissue culture cell lines in vitro ...

Colorado tick fever (CTF) is a disease caused by an RNA virus, Colorado tick fever virus (CTFV). Symptoms, which are often non-specific, begin 3 to 5 days after the bite with an abrupt onset of fever and any of these: headaches, chills, malaise, photophobia, myalgias, nausea, vomiting, diarrhea and abdominal pain. In 5 to 15% of cases a rash occurs. Neurologic complications may also occur. 50% of patients have single recurrence of fever (saddleback fever).. IFA titers for diagnosis. PCR (Polymerase Chain Reaction) is the test most often used to diagnose the disease. CTF is transmitted by Dermacentor andersoni (Rocky Mt. wood tick) which causes illness from the Western Black Hills to the West Coast in the USA.

Serologic Diagnosis of Colorado Tick Fever | The American Journal of Tropical Medicine and HygieneSerologic Diagnosis of Colorado Tick Fever | The American Journal of Tropical Medicine and Hygiene
Abstract Isolation of the virus, the most reliable means of diagnosing Colorado tick fever, is not always practicable. The standard complement-fixation test, using a mouse-brain-derived antigen, may not detect significant rises in antibody titer during the usual 2- or 3-week observation period. Complement-fixation (CF) tests, with antigens derived from infected mouse brains and from an established line of hamster-kidney cells, were compared with a neutralization (plaque-reduction) test and an indirect fluorescent-antibody (IFA) staining test for usefulness in the serologic diagnosis of 34 cases of Colorado tick fever. The cell-culture antigen was as reliable as the mouse-brain antigen, and its preparation was simpler. The CF-antibody titers and the neutralizing-antibody titers tended to be lower and slower to appear than the IFA titers. The IFA method was simple, rapid, and accurate. The IFA titers frequently appeared earlier after onset of illness and reached higher levels than did the CF titers.

In a new paper, Partha Bera and colleagues at NASAs Ames Research Center and Purdue University put these gases under the microscope to find out exactly why they are such powerful heat trappers. They focus on CFCs, HFCs and PFCs - all chemicals containing fluorine or chlorine - that are used in medicine, fridges, and as solvents, among other things. By probing the molecular structure of these compounds, they have found that molecules containing several fluorine atoms are especially strong greenhouse gases, for two reasons. First, unlike many other atmospheric molecules, they can absorb radiation that makes it through our atmosphere from space. Second, they absorb the radiation (and trap the heat) very efficiently, because of the nature of the fluorine bonds inside them. (In technical terms, fluorine atoms create a larger separation of electric charge within the molecule, and this helps the molecular bonds absorb electromagnetic radiation more effectively.) HFCs and other fluorine-based gases ...

I am not sure whether (1) the dopant fluorine atoms group pairwise at iron atoms and (2) if the decorated iron atoms indeed form a superlattice. However, this may be checked experimentally. But then, (3), if there is a superlattice, it is not clear to me why it should be ordered in the way claimed in the paper, with a pattern stacking five unit cells on top of each other for COFFA, for example. There can be many ways to arrange unit cells to form a superlattice with the right supercell volume. This is more obvious in the case of LOFFA, where the supercell comprises 18 unit cells, and there seems to be no a priori reason to select a superstructure which has 6 unit cells stacked on top of each other ...
