New route for synthesis of 2-(2,2-dimethoxyethyl)-1,2,3,4,5,6-hexahydro-1,5-methanoazocino[4,3-b] indole and DFT investigation
(Elsevier Sci Ltd, 2020)
Development of efficient sequences for the synthesis of the title compound (2-(2,2-dimethoxyethyl)-1,2,3,4,5,6-hexahydro-1,5-methanoazocino[4,3-b]indole) (7) was described. The title compound was synthesized through several ...
The electronic and spectroscopic investigation of ( +/- )- Dasycarpidone
(Elsevier, 2020)
(+/-)-Dasycarpidone ((1R,5S)-12-ethyl-2-methyl-1,2,3,4,5,7-hexahydro-6H-1,5-methanoazocino[4,3-b]indol-6one) was investigated by using the quantum chemical calculations. All DFT-based analyses were performed by B3LYP, ...
Synthesis, characterization, UV-Vis absorption and cholinesterase inhibition properties of bis-indolyl imine ligand systems
(Elsevier, 2020)
A number of bis-indolyl imine helical structures has successfully been synthesized employing Schiff base reaction conditions starting from 4,6-dimethoxy-2,3-diphenylindole with different o-phenyl diamines as pi-spacer ...
Electrochemical Characteristics of a Novel Pyridinium Salt as a Candidate Drug Molecule and Its Interaction with DNA
(Wiley-V C H Verlag Gmbh, 2020)
In this article, for the first time, the electrochemical properties of a novel pyridine derivative, 4-(2-(2-hydroxybenzylidene) hydrazinyl)-1-(3-phenylpropyl) pyridinium bromide (abbreviated as 4-Pyri), and its interaction ...
Synthesis of Methylene Bridged Bis-pyrrolo[3,2-c]carbazoles via an Unusual Vilsmeier-Haack Product of N-Ethylcarbazole
(Taylor & Francis Ltd, 2020)
The unexpected result for the formylation of N-ethylcarbazole under the Vilsmeier-Haack conditions (POCl3/DMF) led to the synthesis of novel methylene bridged bis-pyrrolo[3,2-c]carbazoles via Hemetsberger indole synthesis ...
Holonomy-reduced dynamics of triatomic molecules
(Iop Publishing Ltd, 2011)
Whereas it is easy to reduce the translational symmetry of a molecular system using, e. g., Jacobi coordinates, the situation is much more involved for rotational symmetry. In this paper, we address the latter problem using ...
Calculation of eigenvalues and eigenfunctions of a discontinuous boundary value problem with retarded argument which contains a spectral parameter in the boundary condition
(Pergamon-Elsevier Science Ltd, 2011)
In this work, a discontinuous boundary-value problem with retarded argument which contains a spectral parameter in the boundary condition and with transmission conditions at the point of discontinuity is investigated. We ...
Status of High-risk Oncogenic Human Papillomavirus Subtypes Harbored in the Prepuce of Prepubertal Boys
(Elsevier Science Inc, 2012)
OBJECTIVE To evaluate whether the high-risk human papillomavirus (HPV) subtypes that are strongly related to cervical cancer are harbored in the prepuce of the circumcised tissue of prepubertal boys in the period just ...
Ultrasound-guided serratus plane block combined with intercostal block for a high-risk patient with pericardial tamponade: A case report
(Wolters Kluwer Medknow Publications, 2020)
Anesthetic management of patients with pericardial tamponade is challenging. A 65-year-old man diagnosed with small-cell lung carcinoma and bilateral malignant pleural effusion in the lungs and pericardial effusion was ...
Chronic hematoma on the forearm mimicking soft tissue sarcoma
(Springer, 2013)
Chronically expanding hematoma is a rare entity, characterized by its persistence and increasing size. Chronic hematoma may be misdiagnosed as a soft tissue neoplasm due to its large size and slow progression and enlargement. ...
