Isolation of SMTP-3, 4, 5 and -6, novel analogs of staplabin, and their effects on plasminogen activation and fibrinolysis. (1/2765)

Four novel triprenyl phenol metabolites, designated SMTP-3, -4, -5, and -6, have been isolated from cultures of Stachybotrys microspora IFO 30018 by solvent extraction and successive chromatographic fractionation using silica gel and silica ODS columns. A combination of spectroscopic analyses showed that SMTP-3, -4, -5, and -6 are staplabin analogs, containing a serine, a phenylalanine, a leucine or a tryptophan moiety in respective molecules in place of the N-carboxybutyl portion of the staplabin molecule. SMTP-4, -5, and -6 were active at 0.15 to 0.3 mM in enhancing urokinase-catalyzed plasminogen activation and plasminogen binding to fibrin, as well as plasminogen- and urokinase-mediated fibrinolysis. On the other hand, the concentration of staplabin required to exert such effects was 0.4 to 0.6 mM, and SMTP-3 was inactive at concentrations up to 0.45 mM.  (+info)

Novel selective inhibitors for human topoisomerase I, BM2419-1 and -2 derived from saintopin. (2/2765)

Compounds BM2419-1 and -2 were isolated from a culture broth of a fungus Paecilomyces sp. BM2419. It was shown that these novel compounds were artifacts derived from saintopin, a dual inhibitor of topoisomerase I and II by independent processes. In the human topoisomerase I inhibition assay using the recombinant Saccharomyces cerevisiae, BM2419-1 and -2 inhibited selectively the yeast growth dependent on human topoisomerase I induction with IC50 values of 0.3 ng/ml and 6.0 ng/ml, respectively.  (+info)

Apicularens A and B, new cytostatic macrolides from Chondromyces species (myxobacteria): production, physico-chemical and biological properties. (3/2765)

A novel macrolide, apicularen A, was produced by several species of the genus Chondromyces. Initially it was discovered by bioassay-guided RP-HPLC-fractionation of culture extracts of Chondromyces robustus, strain Cm a13. Apicularen A showed no antimicrobial activity, but was highly cytotoxic for cultivated human and animal cells, with IC50 values ranging between 0.1 and 3 ng/ml. A cometabolite of apicularen A, the N-acetylglucosamine glycoside apicularen B, was distinctly less cytotoxic with IC50 values between 0.2 and 1.2 microg/ml, and showed weak activity against a few Gram-positive bacteria. Apicularen A is chemically closely related to the salicylihalamides A and B from the marine sponge Haliclona sp.  (+info)

BE-31405, a new antifungal antibiotic produced by Penicillium minioluteum. I. Description of producing organism, fermentation, isolation, physico-chemical and biological properties. (4/2765)

A new antifungal antibiotic, BE-31405, was isolated from the culture broth of a fungal strain, Penicillium minioluteum F31405. BE-31405 was isolated by adsorption on high porous polymer resin (Diaion HP-20), followed by solvent extraction, precipitation and crystallization. BE-31405 showed potent growth inhibitory activity against pathogenic fungal strains such as Candida albicans, Candida glabrata and Cryptococcus neoformans, but did not show cytotoxic activity against mammalian cells such as P388 mouse leukemia. The mechanism studies indicated that BE-31405 inhibited the protein synthesis of C. albicans but not of mammalian cells.  (+info)

Relationships between the lipophilicity of some 1,4-piperazine derivatives of aryloxyaminopropanols and their beta-andrenolytic activity. (7/2765)

Nineteen 1,4-piperazine derivatives of aryloxyaminopropanol were evaluated with respect to beta-adrenolytic activity. The retention factors obtained from HPLC, RM values obtained from partition TLC and the lipophilic Hansch's (4) constants pi were determined and the compounds were studied with respect to their lipophilicity based on chromatographic properties. The study of the influence of different substituents introduced at the para position on the phenyl ring on the retention factor indicated the log k vs. the number of carbon atoms in R1 substituent to be a linear relationship. Attempts have been made to relate the beta-adrenolytic activity to the lipohydrophilic parameters by deriving a quantitative relationship between them. Significant parabolic correlation was observed between the beta-adrenolytic activity and the logarithm of the retention factor, log k. An analogous relationship was obtained between the beta-adrenolytic activity of the compounds and the RM values obtained from partition TLC as well as Hansch's lipophilic constants pi.  (+info)

Determination of the lipophilicity of active anticonvulsant N-substituted amides of alpha-arylalkylamine-gamma-hydroxybutyric acid. (8/2765)

The lipophilicities of fourteen anticonvulsant active N-substituted amides of alpha-arylalkylamine-gamma-hydroxybutyric acid [I-XIV] have been determined by reversed-phase thin-layer chromatography with a mixture of methanol, TRIS buffer, and acetic acid as the solvent system. The RM value of each compound decreased linearly with increasing concentration of methanol. The partition coefficients (log P) of the amides were calculated by use of the Prolog P module of the Pallas system. Comparison of RM and log P enabled clog P values to be calculated. It was found that the anticonvulsant activity of amides [I-XIV] can be explained on the basis of their lipophilicity.  (+info)

Raynaud's disease, also known as Raynaud's phenomenon, is a medical condition characterized by a temporary decrease in blood flow to the fingers, toes, and sometimes other parts of the body, such as the nose and ears. This can cause the affected area to feel cold, numb, and painful, and may turn white or blue in color. Raynaud's disease is usually triggered by cold temperatures, stress, or emotional stress, and can also be caused by certain medications or medical conditions, such as lupus, scleroderma, or thyroid disorders. In severe cases, Raynaud's disease can lead to tissue damage and even gangrene if blood flow is not restored quickly. Treatment for Raynaud's disease typically involves lifestyle changes, such as avoiding cold temperatures and stress, and medications to improve blood flow and reduce pain. In some cases, surgery may be necessary to treat underlying medical conditions that are causing the symptoms of Raynaud's disease.

The no-reflow phenomenon is a condition that occurs during a heart attack, where blood flow to a part of the heart muscle is restored after a period of ischemia (lack of blood flow), but the blood flow remains impaired or insufficient. This can lead to further damage to the heart muscle and can be a significant factor in the development of heart failure. The no-reflow phenomenon is thought to occur due to the formation of microthrombi (small blood clots) in the coronary arteries, which can obstruct blood flow even after the main blockage has been cleared. Other factors that can contribute to the no-reflow phenomenon include inflammation, edema (swelling), and the release of harmful substances from the damaged heart muscle cells. Diagnosis of the no-reflow phenomenon is typically made during a coronary angiogram, which is a procedure that uses X-rays to visualize the blood vessels in the heart. Treatment options for the no-reflow phenomenon may include medications to dissolve the microthrombi, mechanical devices to improve blood flow, or surgery to open the blocked coronary arteries.
