Aim: Evaluation of the antitumor activity of the new drug Dekoglitz in animals with tumor strains of Sarcoma 45 in comparison with the drug dekocin, from which it was obtained, as well as with 5-fluorouracil and etoposide, and on ovarian tumors (OT) in comparison with the drug dekocin and identification of the effect of Dekoglitz on NA synthesis and internucleosomal DNA degradation. Methods: The study of preparations was carried out on 68 outbred rats with transplanted C-45 and OT tumors. The alkylating effect of the drugs was studied on cells tumor of Sarcoma 180. Results: The antitumor activity of dekoglitz on Sarcoma 45 was high, about 98/96%, with a remission rate of 80%. Its effect was 28-24% higher than that of dekocin. On OT, the effect of decoglitz with intraperitoneal administration reached 89/76% with a remission rate of 40%, with oral administration 96/86% with a remission rate of 60%. Conclusion: The study of the new drug Dekoglitz on animals with a tumor of Sarcoma 45 revealed its higher activity (by 20-27%) in comparison with the original Dekocin, 5-fluorouracil and etoposide with a lower level of side effects. On OT, the effect of Dekoglitz was 35-40% higher, especially after oral administration. Apparently, the great ability to suppress the synthesis of NA and carry out internucleosomal degradation and fragmentation of tumor DNA by the new drugs dekoglitz explains its antitumor efficacy, which is greater than that of Dekocin (K-18) in experiments on tumors.

Hydrazones and their derivatives are very important compounds in medicinal chemistry due to their reported biological activity for the treatment of several diseases, like Alzheimer’s, cancer, inflammation, and leishmaniasis. However, most of the investigations on hydrazones available in literature today are directed to the synthesis of these molecules with little discussion available on their biological activities. With the purpose of bringing lights into this issue, we performed a revision of the literature and wrote this review based on some of the most current research reports of hydrazones and derivatives, making it clear that the synthesis of these molecules can lead to new drug prototypes. Our goal is to encourage more studies focused on the synthesis and evaluation of new hydrazones, as a contribution to the development of potential new drugs for the treatment of various diseases.

Mistletoe Extract

Breast cancer is among the most frequent types of cancer in women worldwide. Current conventional treatment options are accompanied by side effects. Mistletoe is amongst the important herbal medicines traditionally used as complementary remedies. An increasing number of studies have reported anticancer activity of mistletoe extracts on breast cancer cells and animal models. Some recent evidence suggests that cytotoxic activity of mistletoe may be mediated through different mechanisms. These findings provide a good base for clinical trials. Various studies on mistletoe therapy for breast cancer patients revealed similar findings concerning possible benefits on survival time, health-related quality of life (HRQoL), remission rate, and alleviating adverse reactions to conventional therapy. This review provides an overview of the recent findings on preclinical experiments and clinical trials of mistletoe for its cytotoxic and antitumor activity and its effect on HRQoL in breast cancer patients. Moreover, studies investigating molecular and cellular mechanisms underlying antitumor activity of mistletoe are discussed in this paper. The analyzed trials provided evidence that there might be a combination of pharmacological and motivational aspects mediated by the mistletoe extract application which may contribute to the clinical benefit and positive outcome such as improved HRQoL and self-regulation in breast cancer patients.

Research Challenge

From this presentation it becomes apparent that preclinical investigation of new drugs is a multi-disciplinary endeavour. The need for close team work between the various scientists is necessary to meet this complex research challenge successfully. With the development of an ever-increasing number of potent drugs, it is mandatory that the physician responsible for monitoring new drug trials broaden his understanding of preclinical investigations. In doing so, he will soon learn the need for consistent interplay between the preclinical scientist and clinician.

Introduction. In the development and introduction of medicines into production, the aim of pharmaceutical manufacturers is to comply with the principle of «Quality-by-Design» (QbD). The International Council for Harmonisation (ICH) has created a number of GxP standards, which have become the regulatory framework for the development of documentation regulating the requirements for the development and production of drug products for countries focused on bringing their products to the world pharmaceutical market. The analysis of the system of regulation of pharmaceutical stages of development of new drugs in the territory of the Eurasian Economic Union was not considered, but for the formation of a systematic approach to the management of the process of pharmaceutical development it is necessary to describe them.Aim. To analyze the possibility of applying the QbD principle to the process of drug development at domestic pharmaceutical enterprises.Materials and methods. Content analysis of scientific publications, system and comparative analysis, sociological methods of research in the field of pharmaceutical development.Results and discussions. Regulatory state requirements to the organization and conduct of drug development procedures are analyzed and described. A number of systemic and sectoral problems typical for domestic pharmaceutical manufacturers in the organization of the development and implementation of new drug products. It is established that one of the main problems for Russian enterprises was the organization of the process as a whole and its individual procedures. To solve the problem of organization of procedures for the development and implementation of new medicines, we formed a methodological support, developed on the basis of a systematic approach and international requirements from the quality system.Conclusion. The main problem identified by the manufacturers is the lack of methodological support for the organization of the processes of pharmaceutical development and the introduction of new drugs in the part of research going to the stage of preclinical and clinical development. The decisions adopted by the Eurasian Economic Union do not affect such aspects of pharmaceutical development regulation as the organization of processes, their management and methodological support aimed at the implementation of the QbD principle. To solve this problem, we have developed guidelines for the implementation of the processes of pharmaceutical development and the introduction of new drug products, which allowed us to apply unified and formalized approaches to their organization.

Background Although several studies have been conducted and several articles have been published on India's new clinical trial regulations, very few have examined the views of investigators and ethics board members regarding modifications to the previous regulations. Overall, they have neglected to find out the opinions of other relevant professionals, such as research assistants, coordinators, associates, and managers. To our knowledge, no study has yet investigated the awareness and opinions of Indian research professionals on the new 2019 regulations. Objective This study aims to describe the awareness and opinions of Indian research professionals on the new drug and clinical trial regulations. Methods In this cross-sectional, Web-based study, we will conduct an open survey for various Indian research professionals. These professionals will be selected randomly using multiple sources. The survey questionnaires, which have already been validated, were developed using the form function in Google docs. A Web link was generated for participants to take the survey. Descriptive statistics will be shown as means and standard deviations for constant variables, whereas certain variables will instead be shown as numbers and percentages. Results The survey was opened in July 2019. Enrollment has already started and will be completed in three months. The results calculations are expected to begin in October 2019. Conclusions The results of the survey are expected to represent the views of research professionals on the new regulations that will support the development of clinical research and the pharmaceutical industry in India. These regulations are expected to help advance clinical trials, help with the approval of new drugs, and enhance ethical norms in the country.
