Regioselective reactions of organozinc reagents with 2,4- dichloroquinoline and 5,7-dichloropyrazolo[1,5-alpha]pyrimidine

Strategies for controlling the regioselective reactions between 2,4- dichloroquinoline and organozinc reagents are described. 2,4- Dichloroquinoline has been found to react with benzylic zinc and phenylzinc reagents in the presence of catalytic amounts of palladium complexes to exclusively give alpha-substituted products. Several metal salts were examined as an additive for gamma-selective coupling reactions. The most effective additive for selective coupling reaction at the gamma-position has been found to be LiCl. These conditions for alpha- or gamma-selective coupling reactions were applied to the reaction between 5,7-dichloropyrazolo[1,5-alpha]pyrimidine and a biphenylmethylzinc reagent in the synthesis of the angiotensin II receptor antagonists. This regioselectivity should be generally applicable to other alpha,gamma-dichloroazine systems.

In vivo selective modulation of tissue glutathione in a rat mammary carcinoma model

Glutathione (GSH) is known to play a role in cellular sensitivity to some chemotherapeutic agents and to radiation. Depletion of cellular GSH has been demonstrated to result in enhanced toxicity of these drugs, and this approach is being explored in the clinic as a form of biochemical modulation, using the drug buthionine sulfoximine (BSO). The fact that some drug-resistant cell lines have increased glutathione levels, and that enhancing GSH concentrations in animal tissues protects against a variety of xenobiotic agents, suggest a different potential approach to improving anti-cancer therapy. We have examined the efficacy of the cysteine ‘pro-drug’ L2-oxothiazolidine-4 carboxylate (OTZ) at enhancing normal tissue versus tumor GSH. Animals were treated with OTZ or BSO, and the concentrations of GSH in normal tissues and tumor were measured. We found that the presence of the tumor itself decreased bone marrow GSH, but that OTZ significantly increased it in this setting. Interestingly, OTZ administration significantly depleted tumor GSH levels to the same level as did BSO. OTZ could offer a selective biochemical modulation of GSH.

A simple and efficient preparation of novel formaldehyde derivatives

New formaldehyde derivatives were prepared in good yields by a short and versatile route. Several crystal structures of corresponding thioacetic acid esters and thiols were determined. The thioacetates were cleaved under acidic or basic conditions affording the thiols in high yield, thus introducing the new substance classes of N-mercaptomethyl-alkylcarboxamides, N-mercapto- methylsulfonamides, and alkoxymethanethiols.

Conventional and nanotechnology based approaches to combat chronic obstructive pulmonary disease: Implications for chronic airway diseases

Chronic obstructive pulmonary disease (COPD) is the most prevalent obstructive lung disease worldwide characterized by decline in lung function. It is associated with airway obstruction, oxidative stress, chronic inflammation, mucus hypersecretion, and enhanced autophagy and cellular senescence. Cigarette smoke being the major risk factor, other secondary risk factors such as the exposure to air pollutants, occupational exposure to gases and fumes in developing countries, also contribute to the pathogenesis of COPD. Conventional therapeutic strategies of COPD are based on anti-oxidant and anti-inflamma-tory drugs. However, traditional anti-oxidant pharmacological therapies are commonly used to alleviate the impact of COPD as they have many associated repercussions such as low diffusion rate and inappropriate drug pharmacokinetics. Recent advances in nanotechnology and stem cell research have shed new light on the current treatment of chronic airway disease. This review is focused on some of the anti-oxidant therapies currently used in the treatment and management of COPD with more emphasis on the recent advances in nanotechnology-based therapeutics including stem cell and gene therapy approaches for the treatment of chronic airway disease such as COPD and asthma.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Molecular docking, molecular dynamics, and in silico prediction of the toxic potential of primaquine thiazolidinone derivatives

Primaquine thiazolidinone derivatives are proposed as promising antimalarial candidates to be tested as primaquine substitutes. Molecular docking and dynamics simulations were applied in the analogues-NQO2 complexes to understand their interactions, and also studied the toxic potential of these derivatives in a set of 16 target proteins. The results of our study suggest that the interactions of five thiazolidinone primaquine derivatives with NQO2 are stronger than the interaction of primaquine and NQO2. The analogue 5n-protein complex seems to be the most stable compared with the primaquine-protein complex. The analogues 5n and 5o are predicted to be in the same class of toxic potential as primaquine. Their interactions with the cytochrome P450 enzymes are also predicted to be weaker, indicating that a better activity/toxicity balance compared with primaquine may be reached.

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.Electric Literature of 2682-49-7, you can also check out more blogs about2682-49-7
