Pharmacological therapy for acute respiratory distress syndrome

Acute respiratory distress syndrome (ARDS) is an inflammatory process caused by a variety of direct and indirect injuries to the lungs. Despite improvements in supportive care and advances in ventilator management, mortality in patients with ARDS remains high. Multiple pharmacological interventions have been investigated but have not shown improved survival. Clinical trials using corticosteroids, prostaglandins, nitric oxide, prostacyclin, surfactant, lisofylline, ketoconazole, N-acetylcysteine, and fish oil have been unable to show a statistically significant improvement in patient mortality. As more is understood about the pathophysiology of ARDS, treatment strategies statistically as increasing alveolar fluid clearance through activation of sodium channels, enhancing repair of alveolar epithelium with growth factors, inhibiting fibrin deposition, blocking proinflammatory transcription factors, preventing the effect of potent vasocontrictors such as endothelin, and using antibodies against key inflammatory cytokines are being explored. This review focuses on the pharmacological treatments studied clinically, proposed reasons for their lack of success, and new concepts emerging in ARDS therapy.

Recent developments of coumarin hybrids as anti-fungal agents

Fungi place a huge burden on global healthcare systems attributed to the fact that fungal infections are responsible for the high morbidity and mortality rates in patients who received stem cell transplantation, antineoplastic chemotherapy, organ transplants or suffered Human Immunodeficiency Virus (HIV) infection. Unfortunately, almost none of the representative anti-fungal agents currently used in clinical therapy are ideal in terms of efficacy, anti-fungal spectrum or safety. Moreover, the rapid development of resistance to existing anti-fungal drugs has further aggravated the mortality and spread of fungi, creating an urgent need for novel anti-fungal agents. The broad spectrum of biological activities and successful usage in clinic made coumarins a promising anti-fungal candidate. Furthermore, hybridization of other pharmacophores with coumarin motif may enhance the anti-fungal efficacy, broaden the anti-fungal spectrum and improve the safety profiles. Thus, numerous coumarin hybrids have been assessed for their anti-fungal activities, and some of them showed promising potency and may have a novel mechanism of action. This review aims to outline the recent development of coumarin hybrids as potential anti-fungal agents and summarize their Structure-Activity Relationship (SAR) to provide an insight for rational designs of more active agents.

Enantioselective synthesis of structurally intricate and complementary polyoxygenated building blocks of spongistatin 1 (altohyrtin a)

Enantioselective approaches to the construction of four complex building blocks of the structurally intricate marine macrolide known as spongistatin 1 are presented. The first phase of the synthetic effort relies on a practical approach to a desymmetrized, enantiomerically pure spiroketal ring system incorporating rings A and B. Concurrently, the C17-C28 subunit, which houses one-fifth of the stereogenic centers of the target in the form of rings C and D, was assembled via a composite of stereocontrolled aldol condensations. Once arrival at the entire C1-C28 sector had been realized, routes were devised to provide two additional highly functionalized sectors consisting of C29-C44 and C38-C51. A series of subsequent transformations including cyclization of the E ring and hydroboration to afford the B-alkyl intermediate for the key Suzuki coupling to append the side chain took advantage of efficient stereocontrol. Ultimately, complete assembly and functionalization of the western EF sector of spongistatin was thwarted by an inoperative Suzuki coupling step intended to join the side chain to the C29-C44 sector, and later because of complications due to protecting groups, which precluded the complete elaboration of the late stage C29-C51 intermediate.

The design and optimization of a series of 2-(pyridin-2-yl)-1H-benzimidazole compounds as allosteric glucokinase activators

The optimization of a series of benzimidazole glucokinase activators is described. We identified a novel and potent achiral benzimidazole derivative as an allosteric GK activator. This activator was designed and synthesized via removal of the chiral center of the lead compound, 6-(N-acylpyrrolidin-2-yl)benzimidazole. The activator exhibited good PK profiles in rats and dogs, and significant hypoglycemic efficacy at 1 mg/kg po dosing in a rat OGTT model. The binding site and binding mode of the benzimidazole class of GKA with GK protein was confirmed by X-ray crystallographic analysis.

Discovery, synthesis, and structure-activity relationship development of a series of N -4-(2,5-dioxopyrrolidin-1-yl)phenylpicolinamides (VU0400195, ML182): Characterization of a novel positive allosteric modulator of the metabotropic glutamate receptor 4 (mGlu4) with oral efficacy in an antiparkinsonian animal model

There is an increasing amount of literature data showing the positive effects on preclinical antiparkinsonian rodent models with selective positive allosteric modulators of metabotropic glutamate receptor 4 (mGlu4). However, most of the data generated utilize compounds that have not been optimized for druglike properties, and as a consequence, they exhibit poor pharmacokinetic properties and thus do not cross the blood-brain barrier. Herein, we report on a series of N-4-(2,5-dioxopyrrolidin-1-yl) phenylpicolinamides with improved PK properties with excellent potency and selectivity as well as improved brain exposure in rodents. Finally, ML182 was shown to be orally active in the haloperidol induced catalepsy model, a well-established antiparkinsonian model.

Discovery of a COX-2 selective inhibitor hit with anti-inflammatory activity and gastric ulcer protective effect

Aim: A novel series of 2-arylimino-5-arylidenethiazolidin-4-ones 12a-n were synthesized and all the target compounds were fully characterized by IR, 1H NMR, 13C NMR, mass spectroscopy and elemental analysis. Materials & methods: All the target compounds were evaluated for their COX inhibition by enzyme immunoassay kit and in vivo anti-inflammatory activity. Results: Tested compounds were found more potent inhibitors of COX-2 (IC50 = 0.54-3.14 M) than COX-1 (IC50 = 4.97-11.52 M). The ulcerogenic liability of compounds 12(d, e, f, h, k, m) was performed and showed gastric safety more than or comparable to celecoxib. Conclusion: In addition, docking study of the most potent and selective compound 12h into COX-2 active site revealed that this target compound assumed interactions and binding pattern similar to that of as a cocrystallized ligand bromocelecoxib (S-58).
