The aromathecin topoisomerase I (top1) inhibitors offer promising scaffolds for the development of novel cancer chemotherapeutics. They are ‘composites’ of the camptothecin and indenoisoquinoline top1 inhibitors. Interestingly, some structure-activity relationship (SAR) overlap between the aromathecins and the indenoisoquinolines has been observed. For both classes, placement of certain polar groups in similar regions of the heteroaromatic system improves top1 inhibitory and antiproliferative activities. A series of water-soluble aromathecins substituted at position 14 with diaminoalkanes of various lengths has been prepared. These compounds all possess similar antiproliferative potency, but a general trend is observed: aromathecins with longer diaminoalkane substituents (>6 carbons) possess lower anti-top1 activity than their smaller counterparts (2-4 carbons), presumably as a result of unfavorable hydrophobic interactions. This trend is also noted with the indenoisoquinolines, revealing additional SAR overlap that supports the hypothesis that there is a ‘universal’ top1 inhibitor SAR.

Douchi is a traditional fermented soybean food with many beneficial health effects. The aim of this study was to determine the in vitro apoptosis-inducing effect of the volatile components of Douchi (VCD) and to examine the relationship between anticancer effects and VCD. After treatment with 0.4, 0.8, and 1.6 mg/mL VCD for 48 h, the proliferation of human nasopharyngeal carcinoma CNE-1 cells was inhibited, and treatment with 1.6 mg/mL VCD had the highest inhibitory effect(84.6%). Treatment with 0.4 and 0.8 mg/mL VCD also showed good inhibitory effects with the apoptosis rates of 29.7%and 55.6%, respectively. The flow cytometry results showed that 36.2% of the 1.6 mg/mL VCD treated CNE-1 cells in the sub-G1 phase. Reversed transcription-polymerase chain reaction (RT-PCR) analysis indicated that VCD could significantly induce apoptosis in CNE-1 cancer cells (P < 0.05) by upregulating cysteine-aspartic acid protease (caspase)-3, caspase-8,caspase-9, Bax, p53, p21, E2F1, p73 and IkappaB-alpha expression and by downregulating Bcl-2, Bcl-xL, human inhibitor of apoptosis protein (HIAP)-1, HIAP-2 and NF-kappaB mRNA expression in a dose-dependent manner. VCD contained 63 chemical compounds that could potentially cause apoptosis in CNE-1 cells. These results showed that VCD had in vitro apoptosisinducing effects in CNE-1 cells, and this effect was ascribed to the complex chemical composition of VCD.

3-Isocyanoisobenzofuran-1(3H)-ones (phthalides) were prepared in two steps from the corresponding phthalaldehydic acids. The 3-isocyanoisobenzofuran-1(3H)-ones are readily rearranged to the corresponding 3-cyanoisobenzofuran-1(3H)-ones using triflic anhydride and 2,6-lutidine, thus enabling the synthesis of 3-cyanoisobenzofuran-1(3H)-ones without using toxic cyanide. Furthermore their annulation with Michael acceptors results in direct formation of 1,4-naphthoquinols/1,4-naphthoquinones in moderate yields.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Formula: C8H6O3. Introducing a new discovery about 16859-59-9, Name is 3-Hydroxyisobenzofuran-1(3H)-one

The critical temperatures and pressures have been measured by the pulse-heating method for fifteen compounds: benzoic acid, 2-methylbenzoic acid, 3-methylbenzoic acid, 4-methylbenzoic acid, benzaldehyde, 4-methylbenzaldehyde, phenylmethanol, (4-methylphenyl)methanol, 2-carboxybenzaldehyde, 1,3-propanediol, 2,2-dimethyl-1,3-propanediol, methyl tetradecanoate, methyl hexadecanoate, methyl octadecanoate, and (Z)-9-methyl octadecenoate. The experimental critical properties have been compared with those estimated by the Wilson/Jasperson and Marrero/Gani methods.

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.Formula: C8H6O3, you can also check out more blogs about16859-59-9

The influence of the precursor chemical structure on secondary organic aerosol (SOA) formation was investigated through the study of the ozonolysis of two anthropogenic aromatic alkenes: 2-methylstyrene and indene. Experiments were carried out in three different simulation chambers: ICARE 7300L FEP Teflon chamber (ICARE, Orleans, France), EUPHORE FEP Teflon chamber (CEAM, Valencia, Spain), and CESAM evacuable stainless steel chamber (LISA, Creteil, France). For both precursors, SOA yield and growth were studied on a large range of initial concentrations (from a1/460 ppbv to 1.9 ppmv) and the chemical composition of both gaseous and particulate phases was investigated at a molecular level. Gas phase was described using FTIR spectroscopy and online gas chromatography coupled to mass spectrometry, and particulate chemical composition was analyzed (i) online by thermo-desorption coupled to chemical ionization mass spectrometry and (ii) offline by supercritical fluid extraction coupled to gas chromatography and mass spectrometry. The results obtained from a large set of experiments performed in three different chambers and using several complementary analytical techniques were in very good agreement. SOA yield was up to 10 times higher for indene ozonolysis than for 2-methylstyrene ozonolysis at the same reaction advancement. For 2-methylstyrene ozonolysis, formaldehyde and o-Tolualdehyde were the two main gaseous phase products while o-Toluic acid was the most abundant among six products detected within the particulate phase. For indene ozonolysis, traces of formic and phthalic acids as well as 11 species were detected in the gaseous phase and 11 other products were quantified in the particulate phase, where phthaldialdehyde was the main product. On the basis of the identified products, reaction mechanisms were proposed that highlight specific pathways due to the precursor chemical structure. These mechanisms were finally compared and discussed regarding SOA formation. In the case of 2-methylstyrene ozonolysis, ozone adds mainly on the external and monosubstituted double bond, yielding only one C8-and monofunctionalized Criegee intermediate and hence more volatile products as well as lower SOA mass than indene ozonolysis in similar experimental conditions. In the case of indene, ozone adds mainly on the five-carbon-ring and disubstituted CaC double bond, leading to the formation of two C9-and bifunctionalized Criegee intermediates, which then evolve via different pathways including the hydroperoxide channel and form highly condensable first-generation products.

A convergent total synthesis of 13-hydroxyisocyclocelabenzine was developed. (3S)-Methyl 3-amino-3-phenylpropanoate (4) was used as the chiral building block. The 3,4-dihydro-4-hydroxyisoquinolin-1(2H)-one derivative (5), the key fragment for the total synthesis, was prepared by a novel base-catalyzed lactone-lactam ring enlargement (Scheme 3). The resulting target C(13) epimers 3a/3b from macrocyclization (Scheme 4) were separated by repeated flash chromatography. The absolute configuration of the synthetic alkaloid was determined by an X-ray crystal-structure analysis, which enabled us to determine the absolute configuration (9S,13R) for natural 3a with positive [alpha]D.

Leishmaniases are diseases caused by protozoan parasites of the genus Leishmania. Clinically, leishmaniases range from cutaneous to visceral forms, with estimated global incidences of 1.2 and 0.4 million cases per year, respectively. The treatment of these diseases relies on multiple parenteral injections with pentavalent antimonials or amphotericin B. However, these pharmaceuticals are either too toxic or expensive for routine use in developing countries. These facts call for safer, cheaper, and more effective new antileishmanial drugs. In this investigation, we describe the results of the assessment of the activities of a series of isobenzofuran-1(3H)-ones (phtalides) against Leishmania (Leishmania) infantum chagasi, which is the main causative agent of visceral leishmaniasis in the New World. The compounds were tested at concentrations of 100, 75, 50, 25 and 6.25 muM over 24, 48, and 72 h. After 48 h of treatment at the 100 muM concentration, compounds 7 and 8 decreased parasite viability to 4% and 6%, respectively. The concentration that gives half-maximal responses (LC50) for the antileishmanial activities of compounds 7 and 8 against promastigotes after 24 h were 60.48 and 65.93 muM, respectively. Additionally, compounds 7 and 8 significantly reduced parasite infection in macrophages.
