Ketoconazole-p aminobenzoic cocrystal, an improved antimycotic drug formulation, does not induce skin sensitization on the skin of BALBc mice

In recent years, green nanotechnology-based approaches using plant materials have been accepted as an environmentally friendly and cost-effective approach with various biomedical applications. In the current study, AgNPs were synthesized using the seed extract of the Eugenia uniflora L. (E.uniflora). Characterization was done using UV-Visible spectroscopy, X-ray diffraction (XRD), scanning electronic microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) analyses. The formation of AgNPs has confirmed through UV-Visible spectroscopy (at 466 nm) by the change of color owing to surface Plasmon resonance. Based on the XRD pattern, the crystalline property of AgNPs was established. The functional group existing in seed of E.uniflora extract accountable for the reduction of Ag+ ion and the stabilization of AgNPs was investigated. The morphological structures and elemental composition was determined by SEM and EDX analysis. With the growing application of AgNPs in biomedical perspectives, the biosynthesized AgNPs were evaluated for their antibacterial and along with their antidiabetic potential. The results showed that AgNPs are extremely effective with potent antidiabetic potential at a very low concentration. It also exhibited potential antibacterial activity against the three tested human pathogenic bacteria. Overall, the results highlight the effectiveness and potential applications of AgNPs in biomedical fields such as in the treatment of acute illnesses as well as in drug formulation for treating various diseases such as cancer and diabetes. It could be concluded that E. uniflora seed extract AgNPs can be used efficiently for in vitro evaluation of their antibacterial and antidiabetic effects with potent biomedical applications.

Background: Moringa oleifera lam, commonly known as “Sajina”, is an indigenous species to India. In our folk medicine, it is used for the treatment of Canker (cancer). The Moringa oleifera leaf extract contains many phyto-compounds, with some being anti-neoplastic in nature. Objective: Our preliminary study showed that the leaf extract significantly kills cancer cells compared to normal cells. On searching for the new phyto-compound, Bis-isothiocyanatomethyl) benzene was purified and isolated. Methods: The sequential process of fractional distillation, column chromatography, followed by TLC and HPLC is performed for purification. Every fraction from each step was tested on HeLa cell line for evaluating the presence of the phyto-compound. Results and Conclusion: FTIR peak analysis of a single phyto-compound shows the presence of thiocyanate group, aromatic carbon group. 1H & 13C NMR peak analysis along with High-resolution mass spectroscopy (HRMS) calculation confirm the chemical structure with IUPAC name [Bis (Isothiocyanatomethyl) benzene]. Previously, Isothiocyanatomethyl- benzene solely or in conjugation with sugar molecule has been reported, but its dimeric form in nature hasnot yet been published anywhere. It shows anticancer activity by retarding cancer cell growth & inhibits carcinogenesis on HeLa, MCF-7, and MDA-MB-231 cell lines by caspase 3 apoptotic pathway and showed comparatively less cytotoxicity to PBMC cell. It shows anticancer activity almost the same as the market available drug Cis-Platin. Therefore, further extrapolating its activity with different concentrations may result in its use as a drug formulation for the treatment of cancer.

Mechanistic Basis

The gastrointestinal tract (GIT) can be broadly divided into several regions: the stomach, the small intestine (which is subdivided to duodenum, jejunum, and ileum), and the colon. The conditions and environment in each of these segments, and even within the segment, are dependent on many factors, e.g., the surrounding pH, fluid composition, transporters expression, metabolic enzymes activity, tight junction resistance, different morphology along the GIT, variable intestinal mucosal cell differentiation, changes in drug concentration (in cases of carrier-mediated transport), thickness and types of mucus, and resident microflora. Each of these variables, alone or in combination with others, can fundamentally alter the solubility/dissolution, the intestinal permeability, and the overall absorption of various drugs. This is the underlying mechanistic basis of regional-dependent intestinal drug absorption, which has led to many attempts to deliver drugs to specific regions throughout the GIT, aiming to optimize drug absorption, bioavailability, pharmacokinetics, and/or pharmacodynamics. In this Editorial we provide an overview of the Special Issue "Regional Intestinal Drug Absorption: Biopharmaceutics and Drug Formulation". The objective of this Special Issue is to highlight the current progress and to provide an overview of the latest developments in the field of regional-dependent intestinal drug absorption and delivery, as well as pointing out the unmet needs of the field.

Background For asthma strategy, to avoid the aggravation of bronchial inflammation and contraction, the long acting beta agonist (LABA) addition on inhaled corticosteroids (ICS) has been recommended. Objectives To know whether there is any clinical difference between the additional efficacies of Formoterol (FOR) and Tulobuterol (TUL) onto Budesonide (BUD) may be useful for the elderly patients’ asthma treatment strategy. Methods Eighteen outpatients with mild to moderate bronchial asthma with FEV1.0% < 80% treated by intermediate ICS dosages visited Respiratory Division of Nagasaki University Hospital or Isahaya General Hospital, Japan Community Health care Organization were subjected, and were randomly assigned (9 cases per group) to either the FBC group (BUD/FOR 160/4.5 µg, 2 inhalations twice daily) or BUD + TUL group (BUD 200 mcg: 2 inhalations twice daily + TUL 2 mg daily) and were compared in parallel with 2 arms for 12 weeks prospectively. Peak expiratory flow, forced expiratory volume in 1 second, impulse oscillometry (IOS), fractional exhaled nitric oxide (FeNO), Asthma Control Questionnaire, mini-Asthma Quality of Life Questionnaire (mini-AQLQ), and occurrence of adverse reactions were compared. Results The “Fres” of IOS was improved in FBC group (p = 0.03). The “emotion” domain of mini-AQLQ was improved in BUD + TUL group (p = 0.03). Conclusion By changing the drug formulation, the patch was superior in terms of satisfaction, but it was thought that the inhaled combination was superior in improving the respiratory function itself. It is necessary to pay attention to the characteristics of the patient when selecting treatment.

These materials were reinforced by blending with HA-g-PLA (hydroxyapatite-graft-poly lactic acid) and PGA fiber before being tested to confirm its biocompatibility via in vitro (MTT assay) and in vivo animal experiments (i.e., skin sensitization, intradermal intracutaneous reaction, and in vivo degradation tests). Every specimen exhibited suitable biocompatibility and biodegradability for use as resorbable spinal fixation materials.
