Fast regioselective sulfonylation of pyridine/quinoline N-oxides induced by iodine

Fast sulfonylation of pyridine/quinoline N-oxides induced by iodine is demonstrated herein. The regioselective protocol occurs under metal-free conditions in a short reaction time (10 min), exhibiting high efficiency (up to 92% yield) and good compatibility (up to 33 examples). A gram-scale reaction was conducted with only a slight loss of production.

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.Recommanded Product: Isoquinoline N-Oxide, you can also check out more blogs about1532-72-5

SAR Studies Leading to the Identification of a Novel Series of Metallo-beta-lactamase Inhibitors for the Treatment of Carbapenem-Resistant Enterobacteriaceae Infections That Display Efficacy in an Animal Infection Model

The clinical effectiveness of carbapenem antibiotics such as meropenem is becoming increasingly compromised by the spread of both metallo-beta-lactamase (MBL) and serine-beta-lactamase (SBL) enzymes on mobile genetic elements, stimulating research to find new beta-lactamase inhibitors to be used in conjunction with carbapenems and other beta-lactam antibiotics. Herein, we describe our initial exploration of a novel chemical series of metallo-beta-lactamase inhibitors, from concept to efficacy, in a survival model using an advanced tool compound (ANT431) in conjunction with meropenem.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 6624-49-3, help many people in the next few years.Recommanded Product: 6624-49-3

Thiazolyl and benzothiazolyl hydrazones derived from alpha-(N)-acetylpyridines and diazines: Synthesis, antiproliferative activity and CoMFA studies

The synthesis of a series of thiazolyl and benzothiazolyl hydrazones derived from alpha-(A3-acylpyridines, -quinolines, -isoquinolines, -pyridazines, -pyrimidines, and -pyrazines is reported. The stereochemistry of these compounds was determined by NMR spectroscopic methods. The antiproliferative activity of the novel compounds was quantified in tissue culture (melanoma, breast carcinoma, colon adenocarcinoma, epitheloid cervix carcinoma, Burkitt’s lymphoma, leukemia, and hydroxyurea sensitive and resistant myelogenous leukemia sublines). All compounds exhibited profound antiproliferative activity, in particular against Burkitt’s lymphoma cells. Out of this series, compounds 6b, 7b, 7c, 8c and 8i were found to be 13-900 times more potent than hydroxyurea and no cross-resistance to hydroxyurea was observed. A predictive 3D-QSAR model using the CoMFA approach was established.

5-Nitrofuran-2-ylmethyl group as a potential bioreductively activated pro-drug system

5-Substituted isoquinolin-1-ones have been synthesised by one-pot Curtius rearrangement of the corresponding substituted 3-phenylpropenoyl azides and cyclisation. Arylmethylation of the anions of the isoquinolinones with benzyl halides [4-methoxybenzyl chloride, 2-(chloromethyl)furan and 5-nitro-2-(tosyloxymethyl)furan] takes place exclusively at nitrogen. Nitration of 2-(furan-2-ylmethyl)isoquinolin-1-one in strongly acidic medium gives 2-(5-nitrofuran-2-ylmethyl)isoquinolin-1-one, whereas weaker acidic conditions lead to dinitration. Curtius rearrangement of 3-carboranylbutanoyl azide and trapping with 5-nitrofuran-2-ylmethanol gives 5-nitrofuran-2-ylmethyl N-(3-carboranylpropyl)carbamate. Biomimetic reduction of these nitrofuranylmethyl derivatives of anticancer drugs triggers release of the parent drugs. Thus, these nitrofurans have potential applications as pro-drugs for selective release of therapeutic drugs in hypoxic solid tumours.

Axial chirality control during suzuki-miyaura cross-coupling reactions: The tert-Butylsulfinyl group as an efficient chiral auxiliary

An efficient route to a new family of axially chiral biaryl ligands by a Suzuki-Miyaura cross-coupling reaction between ortho,ortho’-disubstituted aryl iodides bearing in ortho position a tert-butyl or p-tolylsulfinyl group and ortho-substituted phenyl boronic acids or esters is described. The comparison between the t-BuSO and p-TolSO groups as chiral controllers is reported. The modularity of the approach is demonstrated by the preparation of a variety of enantiopure axially chiral mixed S/N and S/P ligands.

Non-platinum complexes containing releasable biologically active ligands

Since the discovery of anticancer activity of cisplatin and other transition metal complexes, a lot of compounds have been reported as containing ligand(s) bearing its(their) own biological activity. Nowadays, the complexes containing releasable bioactive ligand(s), for which several terms (e.g., multi-targeted, multi-action or multi-modal) have been introduced, represent one of the hottest topics for the bioinorganic chemists. Herein we focused on rationally designed cytotoxic complexes of platinum-group metals, namely ruthenium, rhodium, palladium, osmium and iridium, which contain releasable bioactive ligand(s). Because a concept of multi-targeted complexes is based on a release and subsequent joint biological effect of multiple species, we concentrate especially on complexes whose fate under the (pseudo)physiological conditions is provably or most likely connected with a release of bioactive ligand(s)/substituent(s) and cytotoxic metal-containing species. Thus, the simultaneous action of the released species ensures various biological profits, such as higher cytotoxic activity, cytotoxicity at different cells (connected with the ability to overcome resistance) or modified processes connected with the mode of action, as compared with the initial complexes without bioactive ligand(s).
