N-heterocyclic derivatives of 2,4-dihydroxybenzcarbothioamide as antimycotic agents

N-heterocyclic derivatives of 2,4-dihydroxybenzcarbothioamide were synthesized from sulfinylbis- (2,4-dihydroxybenzenethioyl) and commercially available heterocyclic amines. The composition and chemical structures were confirmed by IR, 1H NMR, EI-MS, and elemental analysis. For the estimation of potential activity in vitro the MIC values against 15 strains of dermatophytes, yeasts, and molds were determined. The strongest fungistatic potency was found for N-5?-(3?-oxobenzfurylidyne)-2,4-dihydroxybenzcarbothioamide in relation to all tested dermatophyte strains with MIC = 0.48-0.98 mug/mL. On the basis of the spectroscopic data the influence of N-heterocyclic substitution on antimycotic activity is discussed.

Therapeutic importance of synthetic thiophene

Thiophene and its substituted derivatives are very important class of heterocyclic compounds which shows interesting applications in the field of medicinal chemistry. It has made an indispensable anchor for medicinal chemists to produce combinatorial library and carry out exhaustive efforts in the search of lead molecules. It has been reported to possess a wide range of therapeutic properties with diverse applications in medicinal chemistry and material science, attracting great interest in industry as well as academia. It has been proven to be effectual drugs in present respective disease scenario. They are remarkably effective compounds both with respect to their biological and physiological functions such as anti-inflammatory, anti-psychotic, anti-arrhythmic, anti-anxiety, anti-fungal, antioxidant, estrogen receptor modulating, anti-mitotic, anti-microbial, kinases inhibiting and anti-cancer. Thus the synthesis and characterization of novel thiophene moieties with wider therapeutic activity is a topic of interest for the medicinal chemist to synthesize and investigate new structural prototypes with more effective pharmacological activity. However, several commercially available drugs such as Tipepidine, Tiquizium Bromides, Timepidium Bromide, Dorzolamide, Tioconazole, Citizolam, Sertaconazole Nitrate and Benocyclidine also contain thiophene nucleus. Therefore, it seems to be a requirement to collect recent information in order to understand the current status of the thiophene nucleus in medicinal chemistry research.

Allelopathic Potential of Koelreuteria bipinnata var. integrifoliola on Germination of Three Turf Grasses

Allelopathy is very important for the scientific disposition of garden plants. To understand the allelopathic potential of Koelreuteria bipinnata Franch. var. integrifoliola, the germination of Agrostis tenuis Sibth., Festuca arundinacea Schreb. and Lolium perenne L. were determined under laboratory conditions. The results showed that root, stem and leaf aqueous extracts of K. bipinnata var. integrifoliola had allelopathic effects on all three turf grasses, and the allelopathic activity varied according to extract concentrations, test species, and extract sources. Lower extract concentrations did not affect or promoted the germination and initial seedling growth of turf grasses, but the highest concentrations almost had inhibitory effect. The order of allelopathic potentials of the three organs on germination of these receptors was root < stem < leaf. And at the highest concentration of leaf extract, the most strongly inhibition was found in A. tenuis, followed by F. arundinaces and then L. perenne. In addition, according to gas chromatography?mass spectrometry (GC?MS) analysis, the allelopathic potential compounds and their abundance in root, stem and leaf were obviously different. Therefore, the allelopathic compounds may responsible for allelopathy of K. bipinnata var. integrifoliola. These findings suggested that more attention should be paid to the leaf of K. bipinnata var. integrifoliola for the relative higher allelopathic effects. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C3H3NO, you can also check out more blogs about288-14-2

Photoion mass spectrometry of adenine, thymine and uracil in the 6-22 eV photon energy range

Using synchrotron radiation as excitation source in the 6-22 eV photon energy region, a photoionization mass spectrometry study of three nucleic acid bases, adenine, thymine and uracil, revealed VUV-induced degradation pathways of these important biological molecules. The fragmentation patterns, ionization energies and ion appearance energies (AE) are reported, many for the first time, and are compared with results of electron impact and other studies. AE values enabled heats of formation of parent and some fragment ions to be revised or determined for the first time. Thermochemical data, coupled with the observed AEs, were also useful in clarifying dissociative photoionization pathways. The main neutral loss species are HCN for adenine, HNCO and CO for thymine and uracil, but many subsequent and other fragmentation pathways, including some not suggested previously, are observed and discussed. The hyperconjugation properties of the methyl group make CO loss easier in thymine than in uracil. The astrophysically important fragment ion HCNH+ is shown to be formed by several fragmentation pathways in all three nucleobases. The relative importance of competitive fragmentation processes was determined in some cases. Some astrophysical implications concerning the prospects for observation and survival of these nucleic acid bases in the interstellar medium and in meteorites are briefly discussed.

Microbial degradation of sulfamethoxazole in the environment

Sulfamethoxazole (SMX) is one of the most widely applied sulfonamide antibiotics in the world, which is becoming a ubiquitous pollutant in the environment. In this mini-review, the microbial degradation of SMX was briefly reviewed. The performance of the conventional wastewater treatment plants in removing SMX was provided. The microorganisms capable of degrading SMX, including mixed cultures and pure cultures, were presented. The effects of environmental conditions such as temperature, pH, initial SMX concentration, and additional carbon sources on the biodegradation of SMX were discussed. The metabolic pathways of SMX degradation were summarized. Finally, the suggestions were made for further studies.

Azasteroidal Mimics

An azasteroid mimic or an intermediate for the preparation of an azasteroid and azasteroid mimic is formed via an oxocycloalkenyl isoxazolium anhydrobase and its dimer. The dimer can be used to form mono- and dihydrazones, which can be an azasteroid mimic or an intermediate for the preparation of an azasteroid and azasteroid mimic. A method of preparation of the dimer and the azasteroid mimic or an intermediate for the preparation of an azasteroid and azasteroid mimic occurs with hydrazonation and, optionally, a subsequent dehydrazonation. The dimer can be converted by inserting a nitrogen atom into the six membered ring of to a C-17 position cyclohexenone moiety of the dimer to yield a reduced tetrazolo[1,5-a]azepin-8-yl group. A subsequent hydrozone formation at a benzylic ketone can be carried out to generate an azasteroid mimic with a (triazol-4-yl)imino substituent. Monohydrazones can be converted to their thione equivalents.

Synthesis, pharmacological evaluation and molecular docking studies of indanone derivatives

A new series of isoxazole fused indanones were synthesized form indane-1,3-dione. The newly synthesized derivatives were confirmed by IR,1 H NMR, and mass spectral data. The synthesized title compounds were evaluated for analgesic, anti-inflammatory, and antimicrobial activities. The modifications carried out in indanone had a positive effect in anti-inflammatory activity when compared to that of other pharmacological activities. The compounds BD6, BD7, BD9, BD10, and BD11 showed good anti-inflammatory activity when compared to that of standard indomethacin. BD3, BD4, and BD5 compounds possess moderate anti-inflammatory activity. Some compounds possess moderate analgesic and antimicrobial activity. Docking study reveals that isoxazole nucleus is essential for biological activity. It was concluded that the fusion of isoxazole with indanone nucleus will increase anti-inflammatory activity than analgesic and antimicrobial activity.
