Partial resolution of racemic trans‐4‐[5‐(4‐alkoxyphenyl)‐2,5‐dimethylpyrrolidine‐1‐oxyl‐2‐yl]benzoic acids by the diastereomer method with (R)‐ or (S)‐1‐phenylethylamine
Authors: Uchida Yoshiaki , Uematsu Toshifumi , Nakayama Yoichi , Takahashi Hiroki , Tsue Hirohito , Tanaka Koichi , Tamura Rui 
Published: June 2007

AbstractThe partial resolution is described of a series of racemic trans‐4‐[5‐(4‐alkoxyphenyl)‐2,5‐dimethylpyrrolidine‐1‐oxyl‐2‐yl]benzoic acids (1), which are the key intermediates for the synthesis of chiral organic radical liquid crystalline compounds and are crystallized to give racemic compounds. Racemic acid 1 [(±)‐1] with a long alkyl chain (C7 to C13) could be resolved by the conventional diastereomeric salt formation using (R)‐ or (S)‐1‐phenylethylamine (2) as the resolving agent, whereas resolution of (±)‐1 with a short alkyl chain (C4 to C6) was unsuccessful. Use of six equiv of (R)‐ or (S)‐2 for the initial diastereomeric salt formation of (±)‐1 with a C7‐C13 alkyl chain, followed by recrystallization of the resulting salts once or twice, gave 2S,5S‐ or 2R,5R‐enriched 1, respectively, in an ee range of 75–92% and with an overall recovery of 11–27%, based on the original quantity of (±)‐1.

Structures and inclusion properties of racemic and enantiopure dimethyl and diphenyl 9,9′‐bianthryl‐2,2′‐dicarboxylates
Authors: Toyota Shinji , Shimasaki Toshiaki , Hirano Shinya , Kuga Makoto , Toda Fumio 
Published: June 2007

AbstractThe authors prepared the dimethyl and diphenyl esters of 9,9′‐bianthryl‐2,2′‐dicarboxylic acid in racemic and enantiopure (M) forms. The enantiopure dimethyl ester forms inclusion compounds with various organic compounds such as benzene, methanol, phenol, and aniline whereas the racemic form does this only with benzene. No guest molecules are included by the racemic and enantiopure diphenyl esters. These effects of substituents and homochirality on the inclusion properties are discussed on the basis of X‐ray structures of some inclusion and guest‐free compounds.

Published: June 2007

AbstractBackground: Various strategies have been proposed to improve diagnosis and triage of patients with chest pain at low risk, but uncertainty still exists on the optimal combination of diagnostic tools that should be used in this subset of patients.Hypothesis: The aim of this study was to evaluate the incremental benefit of continuous 12‐lead ST‐segment monitoring over that provided by conventional diagnostic tools in patients with chest pain.Methods: Of 232 consecutive patients referred because of chest pain, 52 were classified as low‐risk according to the Agency for Health Care Policy and Research unstable angina guidelines and observed for 12 h with serial cardiac enzymes and electrocardiograms (ECG) (every 3 h). All patients also underwent both echocardiography at entry and continuous 12‐lead ST‐segment monitoring during the observation period.Results: During a mean hospital stay of 3.7 days (range 1‐14 days), a benign outcome was observed in 37 patients (71%), whereas 15 patients (29%) had major cardiac events or recurrence of chest pain of ischemic origin. Addition of ST‐segment monitoring findings to baseline clinical data as well as to serial enzymes and ECG features added significant incremental prognostic value (p < 0.001). Multivariate analysis showed reproduction of pain by chest pressure (p < 0.05) and presence of ST‐segment changes (≥ 0.1 mV) during 12‐lead ST‐segment monitoring (p < 0.001) as independent predictors of a benign or unfavorable outcome.Conclusions: In low‐risk patients with chest pain, continuous 12‐lead ST‐segment monitoring provides significant incremental diagnostic and prognostic information to currently used clinical, enzymatic, and ECG data, and is helpful in identifying the subset of patients with a worse in‐hospital outcome.

Published: June 2007

AbstractBackground: Diabetic patients undergoing coronary interventional procedures are at increased risk of restenosis and adverse clinical events. The relative impact of stents compared with balloon angioplasty on the outcome of percutaneous intervention in diabetics remains controversial.Hypothesis: The goal of this study was to determine whether stent placement was superior to balloon angioplasty in reducing restenosis of diabetic patients undergoing coronary intervention.Methods: The STRESS Trial was a prospective randomized comparison of stent placement and balloon angioplasty in the treatment of new native coronary lesions. Of 594 randomized patients, 92 (16%) were diabetic. In this substudy analysis of the STRESS Trial, the outcomes after stenting and balloon angioplasty in diabetic patients were compared. The primary endpoint was restenosis as determined by angiography at 6 months. Clinical outcomes at 1 year were assessed.Results: Procedural success was achieved in 82% of diabetic patients assigned to angioplasty and in 100% assigned to stenting (p <0.01). Compared with angioplasty, stenting resulted in a larger postprocedural lumen diameter (2.34 ± 0.44 vs. 1.87 ± 0.52 mm, p < 0.001) and greater acute luminal gain (1.61 ± 0.47 vs. 1.06 ± 0.46 mm, p < 0.001). At 6 months, stenting conferred a larger lumen (1.69 ± 0.57 vs.1.38 ± 0.60 mm, p = 0.03) and greater net luminal gain (0.97 ± 0.55 vs. 0.52 ± 0.52 mm, p < 0.001). Restenosis occurred in 60% of the angioplasty group and in 24% of the stent group (p < 0.01). This was accompanied by a lower need for repeat target vessel revascularization after stenting (31 vs. 13%, p < 0.03).Conclusions: Compared with balloon angioplasty, stent placement in diabetic patients with focal de novo lesions resulted in superior procedural results, reduced restenosis, and improved clinical outcome with fewer repeat revascularization procedures.

AbstractBackground: The relationship between plasma biologic markers and coronary artery remodeling is unknown.Hypothesis: Plasma biologic markers are associated with coronary artery remodeling.Methods: Preintervention intravascular ultrasound images were obtained in 44 patients with chronic stable angina. Plasma samples were collected 24 h before coronary intervention. The biologic markers included total cholesterol, low‐density lipoprotein (LDL) cholesterol, triglyceride, high‐density lipoprotein (HDL) cholesterol, lipoprotein(a) [LP(a)], C‐reactive protein (CRP), and homocysteine. The remodeling index (RI) was defined as a ratio of the (lesion/ proximal reference) external elastic membrane cross‐sectional area. Positive remodeling was defined as an RI > 1.05, negative remodeling as an RI < 0.95, and intermediate remodeling as an RI between 0.95 and 1.05.Results: Total cholesterol level (r = 0.092, p = 0.557), LDL cholesterol level (r = 0.123, p = 0.426), triglyceride level (r = 0.020, p = 0.901), HDL cholesterol level (r = 0.042, p = 0.789), LP(a) level (r = 0.062, p = 0.729), and CRP level (r = 0.266, p = 0.089) did not significantly correlate with the RI. However, the plasma homocysteine level positively correlated with the RI (r = 0.398, p = 0.008). The plasma homocysteine level was significantly lower in the lesions with negative remodeling and higher in the lesions with positive remodeling (10.8 ± 0.7 μmol/l in negative remodeling, 13.1 ± 0.6 μmol/l in intermediate remodeling, and 18.1 ± 2.8 μmol/l in positive remodeling, p = 0.021).Conclusions: Elevated homocysteine levels might be associated with coronary artery remodeling in patients with stable angina.
Comparison between ventricular gradient and a new descriptor of the wavefront direction of ventricular activation and recovery

Published: June 2007

AbstractBackground: Total R T cosine (TCRT) is a new descriptor of repolarization heterogeneity that quantifies the deviation between the directions of ventricular depolarization and repolarization. It revives the old concept of ventricular gradient (VG).Hypothesis: Our goal was to examine whether TCRT and VG contain nonredundant information by comparing their reaction to autonomic tests, namely, postural changes and Valsalva maneuver.Methods: Digital 12‐lead electrocardiograms were recorded in 16 patients with cardiovascular syndrome X (SX, chest pain, exercise‐induced ST‐depression, normal coronary arteries, 3 men, age 60 ± 9 years) and 40 healthy volunteers (31 men, age 33 ± 7 years) during postural changes and Valsalva maneuver. The angle (VGA) [°] and magnitude (VGM) [ms.mV] of VG in reconstructed XYZ leads and TCRT (average cosine of the angles between the QRS and T vectors in mathematically reconstructed three‐dimensional space) were calculated.Results: (mean ± standard of the mean): In healthy subjects, VGM and TCRT decreased, whereas VGA increased in the sitting and standing compared with supine position (TCRT: 0.61 ± 0.05, 0.47 ± 0.06, 0.29 ± 0.08, supine, sitting, and standing, p < 0.05) and during phase II Valsalva (TCRT: 0.47 ± 0.06 vs. 0.61 ± 0.05, p < 0.01 in supine, 0.24 ± 0.08 vs. 0.37 ± 0.07, p < 0.01 in standing). In patients with SX, VGM decreased in the standing position, VGA did not change significantly, while TCRT decreased only in patients without T‐wave abnormalities (n = 9) (TCRT in standing and supine: 0.55 ± 0.09 vs. 0.68 ± 0.08, p < 0.05). VGM increased during Valsalva in patients with SX. Total R T cosine correlated strongly with VGA (r = –0.84, p< 0.00001) and, unlike VGM, did not correlate with heart rate.Conclusions: Ventricular gradient and TCRT contain non‐redundant information. In healthy subjects, they react sensitively to autonomic provocation. In patients with SX, their reaction is attenuated, which suggests disturbance of the autonomic control of repolarization.
