Thermodynamic control synthesis of spiro[oxindole-3,3'-pyrrolines] via 1,4-dipolar cycloaddition utilizing imidazo[1,5-a]quinoline.

A series of novel 2-(quinolin-2-yl)-spiro[oxindole-3,3'-pyrrolines] were synthesized by one-pot three-component reaction involving dimethyl acetylenedicarboxylate, 1-phenylimidazo[1,5-a]quinoline and N-alkylisatins in chloroform at ∼60 °C for 24 h. Structures of these new spiro derivatives were deduced from HRMS and NMR spectral data. A plausible mechanism for the observed thermodynamic control pathway is presented herewith. Interestingly, the spiro adduct, derived from 5-chloro-1-methylisatin, exhibited excellent antiproliferative activity on MCF7, A549 and Hela human cell lines (IC50 ≃ 7 µM).

A preliminary clinico-epidemiological portrayal of COVID-19 pandemic at a premier medical institution of North India.

CONTEXT: The outbreak and spread of severe acute respiratory syndrome coronavirus 2 has led to a global exigency of colossal and monstrous proportions in terms of public health and economic crisis. Till date, no pharmaceutical agent is known to manage in terms of prevention and treatment of coronavirus disease 2019 (COVID-19), the disease caused by a novel virus. AIMS: The aim of the present work was to understand the underlying disease profile and dynamics that could provide relevant inputs and insight into pathophysiology and prevent further spread and evolve management strategies of COVID-19 patients from data-driven techniques. SETTINGS AND DESIGN: A retrospective observational descriptive study was conducted on 29 COVID-19 patients admitted at a premier medical institution of North India in the months of February and March 2020. METHODS: The patients were diagnosed with reverse transcription-polymerase chain reaction test. Demographic, clinical, and laboratory data were collected. RESULTS: The mean age of population was 38.8 years with male preponderance, of which two patients were residents of Italy, and others hailed from semi-arid and Western sandy arid regions of Rajasthan (urban population). The major presenting symptom complex of said COVID-19 sample population included fever (48%), cough (31%), and shortness of breath (17%). Most of the patients (83%) had no comorbidity. No clinical correlation (r) could be appreciated between the duration of test positivity and age of afflicted COVID-19 patients (r = -0.0976). CONCLUSIONS: The present evaluation of various facets of the ongoing global pandemic of COVID-19 is an attempt to portray early clinical and epidemiological parameters of the menace of COVID-19 patients admitted at SMS Medical College and Attached Hospitals, Jaipur.

Incidence and risk factors for cytomegalovirus (CMV) reactivation following autologous hematopoietic stem cell transplantation in children.

There are limited data on the incidence of CMV reactivation following autologous HSCT (AHSCT) in children. We retrospectively reviewed the incidence and risk factors for CMV reactivation in 72 children who received AHSCT. Twenty-two patients (31%) had positive CMV antigenemia at a median of 23 days (12-31) following transplant. Four patients (6%) required preemptive therapy and all episodes resolved. None of the patients developed CMV disease. Only being CMV seropositivity prior to transplant was significantly associated with CMV reactivation (P < 0.001). The incidence of CMV reactivation following pediatric AHSCT is low, and surveillance beyond 30 days is not needed.

A randomized placebo controlled trial of Inolter (herbal product) in the treatment of type 2 diabetes.

OBJECTIVE: To evaluate the safety and effectiveness of Inolter in achieving glycemic control and changes in lipid profile of newly diagnosed type 2 diabetics. STUDY DESIGN: A randomized, placebo-controlled double blind. Sixty newly diagnosed patients of type-2 diabetes were randomized. Of these, 30 were put on Inolter monotherapy and 30 patients on placebo. Efficacy of Inolter was determined by observing glycemic control by estimating glycosylated haemoglobin (HbA1c) and fasting blood sugar (FBS), alteration of lipid profile by serum cholesterol, LDL, VLDL, HDL and triglycerides. STATISTICAL METHODS: Student's unpaired 't' test. RESULTS: Patients compliance was satisfactory and no adverse effects were observed. Better hypoglycemic effect was observed with Inolter both respect to fasting blood sugar (mean 65.4 +/- 63.72 mg/dl) compared to placebo (mean 26.45 +/- 38.3 mg/dl) (p < 0.001). The mean change, with Inolter, in serum cholesterol (21.33 +/- 26.05 mg/dl), serum triglyceride (30.36 +/- 32.62 mg/dl), VLDL (8.85 +/- 3.25 mg/dl), LDL (10.00 +/- 4.48 mg/dl) and HDL (-2.33 +/- 5.66 mg/dl) was also significantly different (p < 0.001) from those given placebo, where it was 15.7 +/- 20.14 mg/dl, 8.70 +/- 13.24, 0.10 +/- 4.10 mg/dl, -0.70 +/- 4.58 mg/dl and 0.65 +/- 0.00 mg/dl, respectively. CONCLUSION: Inolter appears to be an useful adjunctive therapy to exercise and diet control in newly diagnosed type 2 diabetes mellitus.
