Background
Due to the discovery that deep venous thrombosis (DVT) inhibitor is of chemotherapeutic importance, the nano-property of dimethyl 2,2'-[2,2'-(ethane-1,1-diyl) bis(1
H-
indole-3,2-diyl)]-diacetate (DEBIC), a recently reported antitumor agent, is worthy of
A set of ten 2-phenyl-3-(quinolizidin-1-yl)-5-substituted indoles was prepared through the Fischer cyclization of lupinyl- and epi-lupinylphenylketone 4-substituted phenylhydrazones. Compounds were tested for antiaggregating activity on human platelets activated by adenosine diphosphate (ADP),
5-(1-Methyl-4-phenyl-imidazol-5-yl)indoles 5 were prepared and tested as analogs of the natural vascular-disrupting agent combretastatin A-4 (CA-4). The 3-bromo-4,5-dimethoxyphenyl derivative 5c was far more active than CA-4 with low nanomolar IC50 concentrations against multidrug-resistant
Antifibrinolytic agents are required during complex surgeries to decrease bleeding; their pro-thrombotic potency and efficacy in causing hemostasis has attracted much attention. To discover new inhibitors of urokinase with high selectivity for antifibrinolytic effects over pro-thrombotic effects,
Lamprocapnos spectabilis (L.) Fukuhara is a perennial plant species valued in the horticultural, cosmetic, and pharmaceutical markets. To date, however, there were no studies on tissue culture systems in this species when adjusted from non-meristematic explants. The aim of this study is to
Both in the male and in the female reproductive tract glucose can be converted via either the pentose pathway or the sorbitol pathway. It is shown that a disturbed carbohydrate metabolism can lead to infertility, i.e. in the cow and in the bull semen. Evidence is provided that the serotonin-like
All strains of Escherichia coli isolated from cases of hemorrhagic colitis and sent to the Centers for Disease Control, Atlanta, Ga., over a 3-year period were assayed for toxicity in Vero cell cultures. Strains that produced moderate or high levels of verotoxin were characterized by serotype,
Indole-3-carbinol (I-3-C) was examined for its ability to protect mice against 24-hr N-nitrosodimethylamine (NDMA)-mediated hepatotoxicity. NDMA (20 mg/kg body weight) alone produced extensive hemorrhagic and centrolobular necrotic lesions, with a necrotic severity index of 3.0 +/- 0.4 (scale of
Cytotoxin-producing Klebsiella oxytoca is the causative agent of antibiotic-associated hemorrhagic colitis (AAHC). Recently, the cytotoxin associated with AAHC was identified as tilivalline, a known pentacyclic pyrrolobenzodiazepine (PBD) metabolite produced by K. oxytoca Although this assertion of
The development of small molecule inhibitors targeting GPVI has promising therapeutic role, as they inhibit arterial thrombosis with limited risk of bleeding. Among the compounds showing in vivo antithrombotic activity, the most active compound 6b (ED50 = 28.36 μmol/kg po in mice) showed improved
The GPVI receptor on the platelets plays a major role in inhibiting arterial thrombosis with limited risk of bleeding and is considered a potential anti-thrombotic target for arterial thrombosis. In the reported anti-thrombotics, tetrahydropyridoindoles, the title compound was the best inhibitor of
Spiropiperidine indoline-substituted diaryl ureas had been identified as antagonists of the P2Y1 receptor. Enhancements in potency were realized through the introduction of a 7-hydroxyl substitution on the spiropiperidinylindoline chemotype. SAR studies were conducted to improve PK and potency,
As a preface to a general discussion of these experiments, we wish to refer again briefly to the titrations of virulence described in this paper. None of them was carried out in an altogether proper manner,- it was necessary to employ rabbits of mixed breed, to use small numbers, and in some
Cigarette smoking and alcohol consumption possibly affect platelet functions. To verify the hypothesis that some α-, β-, and γ-carboline components in cigarette smoke and alcoholic beverages may change platelet aggregability, their effects on human platelets were determined by aggregometry together
A medium for direct overnight isolation of hemorrhagic colitis (HC) strains of Escherichia coli from foods has been developed. It is a direct plating medium incorporating tryptophan (as tryptone), sorbitol, an indicator dye and a fluorogenic substrate for diagnostic purposes. Sodium chloride is
