The 5-hydrazino-3-methylisothiazole-4-carboxylic acid, its new 5-substituted derivatives and their antiproliferative activity

Currently, the basic method of treatment of colon cancer is surgery. The range of anticancer drugs used in the treatment of colorectal cancer is small and is based mainly on systemic combination chemotherapy. As a result of the designed syntheses, we received new isothiazole derivatives with anticancer activity. The synthesized 5-hydrazino-3-methylisothiazole-4-carboxylic acid has never been obtained before. It is also a substrate for the synthesis of its innovative derivatives, i.e. compounds that are Schiff bases. The identification of the structure of new compounds was carried out using mass spectrometry (MS), proton nuclear magnetic resonance spectroscopy (H-1 NMR), carbon nuclear magnetic resonance spectroscopy (C-13 NMR) and infrared spectroscopy (IR). Potential antitumor activity was confirmed in antiproliferative MTT and SRB tests. The selected, most biologically active substances were characterized by high selectivity towards leukemia and colon cancer cell lines. They caused high inhibition of proliferation of human biphenotypic B cell myelomonocytic leukemia MV4-11 (13 compounds), human colon adenocarcinoma cell lines sensitive LoVo (8 compounds) and resistant to doxorubicin LoVo/DX (12 compounds). However, in the conducted studies, their activity against breast adenocarcinoma MCF-7 and normal non-tumorigenic epithelial cell line derived from mammary gland MCF-10A was substantially lower. The result of this work is claimed Polish patent application.

Isothiazoles. Part XV. A mild and efficient synthesis of new antiproliferative 5-sulfanylsubstituted 3-alkylaminoisothiazole 1,1-dioxides

5-Sulfanyl-3-alkylaminoisothiazole dioxide derivatives have been identified as a new class of potent inhibitors of rat aortic myocite proliferation. They were prepared by applying a simple methodology able to introduce a heteroatom on C-5 of the 3-alkylaminoisothiazole dioxide system. 3-Aminosubstituted-5-chloroisothiazole dioxides react smoothly not only with S-nucleophiles but also with N- and O-nucleophiles affording the corresponding 5-heterosubstituted isothiazole dioxides through an addition-elimination reaction. The behavior of 3-alkylamino-4-bromo-isothiazole 1,1-dioxide with S-, N- and O-nucleophiles affording the same products has also been described. On the contrary, the 3amino-4,5-unsubstituted isothiazole dioxide system reacts easily only with sulfur nucleophiles affording the corresponding 4,5-dihydro-5 -sulfanylderivatives through a simple Michael addition reaction.

Structural modifications and biological evaluation of 3-isoxazolylvinylcephalosporins

Structural modifications and biological evaluations of 3-isoxazolylvinylcephalosporins (I) were performed. The replacement of a hydrogen atom at the 7-aminothiazole group by a chlorine resulted in an improvement: of the activity against resistant Gram-positive bacterial strains including the methicillin-resistant Staphylococcus aureus (MRSA) and the ciprofloxacin-resistant Staphylococcus aureus (CRSA). The introduction of other heterocycles such as an isothiazole or a thiadiazole in place of the isoxazole moiety gave slightly decreased in vitro activities. (C) 2000 Elsevier Science Ltd.

SYNTHESIS AND ANTIMICROBIAL ACTIVITY OF NEW 3,5-DIAMINOISOTHIAZOLE DERIVATIVES

The 3,5-diaminoisothiazole derivatives 23-42 were synthesized in excellent yields by oxidative cyclization of 3-amino-3-(dialkylamino)propenethioamide derivatives. These intermediates and the isothiazole derivatives were tested in vitro for their antimicrobial activity.

SYNTHESIS OF NEW FLUORESCENT DYES FROM 6-METHOXY-1-CHLORO-3,4-DIHYDRONAPHTHALENE-2-CARBOXALDEHYDE

The synthetic utility of the Vilsmeier reagent to generate new precursors for condensed heterocycles has been extended to the synthesis of some new fluorescent compounds. 6-Methoxy-1-chloro-3,4-dihydronaphthalene-2-carboxaldehyde was used to synthesise new benzimidazo-[1,2-a]-quinolines, quinazolines, thienylbenzimidazole, benzo-[h]-quinolines, benz-[g]-indazoles and isothiazole derivatives. The efficacy of the aldehyde derivative was further extended to synthesise strongly fluorescent pyrano, iminothiopyrano and exocyclic dicyano derivatives. The compounds were characterised by IR, H-1-NMR and visible absorption-emission spectra; they were also applied to polyester as fluorescent dyes and their properties evaluated.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 99-75-2, in my other articles. Category: isothiazole.

Potent Inhibitors of Acetyltransferase Eis Overcome Kanamycin Resistance in Mycobacterium tuberculosis

A major cause of tuberculosis (TB) resistance to the aninoglycoside kanamycin (KAN) is the Mycobacterium tuberculosis (Mtb) acetyltransferase Eis. Upregulation of this enzyme is responsible for inactivation of KAN through acetylation. of its amino;groups. A 123 000 compound high-throughput screen (HTS);yielded several small-molecule Eis inhibitors 014 share an isothiazole S,S-dioxide hoteroeyelic core. TheSe were investigated for their, structure attiliity relationships.: Crystal structures of Eis in,complex with two potent inhibitorS show that these molecules are bound in the conformationally :adaptable aminoglycoSide binding site of the enzyme, thereby obstructing binding of KAN for acetylation. Importantly; we demonstrate that several Eis inhibitors, when used in combination with KAN against resistant Mtb, efficiently overcome KAN resistance. This approach paves the way:toward development of novel combination, thetapies against aminoglycoside-resistant TB.
