annualreviews.org/page/journal/pubdates for revised estimates.Background A valine carbamate prodrug (7-P) was designed to enhance the low bioavailability of daidzein due to its low water solubility and membrane permeability. Here, we developed a high-throughput HPLC-MS/MS method to measure daidzein and its 7-O-glucuronide after oral administration of daidzein or 7-P. Materials & methods A HPLC-MS/MS method was validated and successfully applied to assess the pharmacokinetic behavior of daidzein and its 7-O-glucuronide after orally administrating daidzein or 7-P. The validated method on selectivity, linearity (r ≥ 0.995), precision (relative standard deviation 92.4%), matrix effect ( less then 8.2%) and stability were satisfied. Conclusion The proposed economical, rapid and sensitive method will be an alternative analytical procedure for daidzein and its metabolite in biological samples.
Compare the effectiveness of two educational teaching methods for diabetic patients.

Quasi-experimental study comparing two interventions using a pretest/post-test design.

Three clinics within a western U.S. regional health system.

818 adult diabetic participants (60.5 mean age, 52% female) attended one to four sessions between 2013-2017, and had A1c tests within 180 days of first attended session and 30 to 365 days after last attended session.

A group-based, highly interactive learning experience (n = 561) and a traditional, lecture-style class (n = 257).

Pre and post measures of A1c.

Paired t-tests measured change within each group pre-post intervention. Two-sample t-tests measured mean change pre-post intervention between the two groups. Multivariable linear regression measured mean change in A1c between groups, adjusted for pre-test scores and controlling for demographic variables.

Both interactive and traditional teaching interventions were effective at significantly reducing patient A1c levels by 1.3 (
< 0.001) and 1.0 (
< 0.001) points respectively. The between groups difference in A1c was not significant, t(512) = 1.66,
= 0.0985, but when controlling for age, pre-A1c and days post-A1c, the interactive intervention was significantly (
< 0.05) more effective reducing patient A1c levels by 0.19 points than the traditional intervention.

Group-based, interactive diabetes self-management education programs may be an effective model for reducing patient A1c levels.

This novel synthetic strategy offers an alternative method for the construction of aposafranones and their N-oxides are meaningful in the fields of both biology and organic synthesis. The established protocol explores the annulation scope of enaminones, and it expands the application of nitro-based cyclization.Herein we reported a novel phosphine-catalyzed (4 + 2) cyclization reaction of electron-deficient conjugated dienes with enones to generate functionalized dihydropyran skeletons. Tamoxifen A mechanistic investigation reveals that the reaction produces a new phosphonium zwitterion, which undergoes consecutive reactions. In addition, an asymmetric variant was developed by efficient and economical chiral phosphine catalysis.Malaria-causing Plasmodium parasites are developing resistance to antimalarial drugs, providing the impetus for new antiplasmodials. Although pantothenamides show potent antiplasmodial activity, hydrolysis by pantetheinases/vanins present in blood rapidly inactivates them. We herein report the facile synthesis and biological activity of a small library of pantothenamide analogues in which the labile amide group is replaced with a heteroaromatic ring. Several of these analogues display nanomolar antiplasmodial activity against Plasmodium falciparum and/or Plasmodium knowlesi, and are stable in the presence of pantetheinase. Both a known triazole and a novel isoxazole derivative were further characterized and found to possess high selectivity indices, medium or high Caco-2 permeability, and medium or low microsomal clearance in vitro. Although they fail to suppress Plasmodium berghei proliferation in vivo, the pharmacokinetic and contact time data presented provide a benchmark for the compound profile likely required to achieve antiplasmodial activity in mice and should facilitate lead optimization.Chlorination with chlorine is straightforward, highly reactive, and versatile, but it has significant limitations. In this Letter, we introduce a protocol that could combine the efficiency of electrochemical transformation and the high reactivity of chlorine. By utilizing Cl3CCN as the chloride source, donating up to all three chloride atom, the reaction could generate and consume the chlorine in situ on demand to achieve the chlorination of aromatic compounds and electrodeficient alkenes.The vicinal diamine motif plays a significant role in natural products, drug design, and organic synthesis, and development of synthetic methods for the synthesis of diamines is a long-standing interest. Herein, we report a regioselective intermolecular three-component vicinal diamination of styrenes with acetonitrile and azodicarboxylates. The diamination products can be produced in moderate to excellent yields via the Ritter reaction. Synthetic applications and theoretical studies of this reaction have been conducted.A unique catalytic asymmetric C-7 Friedel-Crafts alkylation/N-hemiacetalization cascade reaction of 4-aminoindoles with β,γ-unsaturated α-keto esters has been described. Using a chiral magnesium H8-BINOL-derived bis(phosphate) complex as catalyst, the resulting functionalized 1,7-annulated indole scaffolds are obtained in high yields (up to 98%) and with good to excellent enantioselectivities (up to 99%) and diastereoselectivities (up to >201) under mild reaction conditions.
