Symbiodinolide time-resolved absorption and resonance ft-ir and raman biospectroscopy and density functional theory (dft) investigation of vibronic-mode coupling structure in vibrational spectra analysis

Abstract

Parameters such as FT -IR and Raman vibrational wavelengths and intensities for single crystal Symbiodinolide are calculated using density functional theory and were compared with empirical results. The investigation about vibrational spectrum of cycle dimers in crystal with carboxyl groups from each molecule of acid was shown that it leads to create Hydrogen bonds for adjacent molecules. The current study aimed to investigate the possibility of simulating the empirical values. Analysis of vibrational spectrum of Symbiodinolide is performed based on theoretical simulation and FT-IR empirical spectrum and Raman empirical spectrum using density functional theory in levels of HF/6-31G * , HF/6-31++G ** , MP2/6-31G, MP2/6-31++G ** , BLYP/6-31G, BLYP/6-31++G ** , B3LYP/6-31G and B3LYP6-31-HEG ** . Vibration modes of methylene, carboxyl acid and phenyl cycle are separately investigated. The obtained values confirm high accuracy and validity of results obtained from calculations.Molecular structure of Symbiodinolide .Heidari A (2019) Symbiodinolide time-resolved absorption and resonance ft-ir and raman biospectroscopy and density functional theory (dft) investigation of vibronic-mode coupling structure in vibrational spectra analysis

Okadaic Acid Time-Resolved Absorption and Resonance FT-IR and Raman Biospectroscopy and Density Functional Theory (DFT) Investigation of Vibronic-Mode Coupling Structure in Vibrational Spectra Analysis

“…The high release of histamine due to allergic reactions is regulated by histamine H1 receptor [233][234][235]. Histamine affects the immune response and related functions in human through H1, H2, H3 and H4 receptors activation with their intracellular signals [236][237][238]. The present research work demonstrates the chemotaxonomy of such valuable plant, from the genus of Okadaic acid.…”

“…Oxidative stress causes cell damage leading to various health issues such as chronic disease, cancer, autoimmune disorders, aging, cataract, rheumatoid arthritis, cardiovascular diseases, neurodegenerative diseases, respiratory disorders [210][211][212][213][214][215][216][217][218] and also the induced oxidative stress causes bronchial contraction by the release of cyclooxygenase and lipoxygenase in the airway that leads to bronchial asthma in human [219][220][221][222][223][224][225]. Asthma is a chronic inflammatory lung disease that happens due to the respiratory infection triggered by the inhalation of allergens like tobacco smoke, air pollutants, genetic and environment factors [226][227][228][229][230][231][232] which leads to the release of histamine and leukotrienes from the mast cell in the lung. The high release of histamine due to allergic reactions is regulated by histamine H1 receptor [233][234][235].…”

“…For this purpose, genetic algorithm with an objective function based on data sparsity and statistical concepts. The proposed method is implemented and results indicate high accuracy of this algorithm in selecting effective features and increasing accuracy of the classifier compared to basic methods and other studies [285][286][287][288][289][290][291][292][293][294][295][296][297][298][299].…”

“…So, drug schedules must be balanced between the reducing of tumor cells, drug concentration and drug toxicity during fixed period of treatment with no drug resistant. Two drug scheduling types are presented in this work, continuous and discontinuous [280][281][282][283][284][285][286][287]. HBMO that is a nature inspired algorithm which simulates the process of real honey-bees mating, is used to optimize the dose quantities with rest periods (periods of treatment that chemotherapy is stopped).…”
