The alarming increase in the development of drug resistant microbes and the decrease in the efficacy of numerous antibiotics have led to the rise in patient mortality and morbidity affecting various fields of medicine. To combat this development and or the improvement of drugs are paramount. Natural products have long been utilized in the treatment of diseases showing broad spectrum of activity against a wide range of pathogens. In this study, the potential application of propolis to combat drug resistant microbes is reviewed, highlighting the presence and diversity of bioactive compounds with focus on its antimicrobial activity against a number of drug resistant microbes and its synergistic properties with other antimicrobial compounds. It is hoped that this study would enable researchers to continue to analyse propolis compounds and its interactions with other antimicrobial compounds which ultimately paves the way for new drug development.

Oral cancer is one of the most common types of cancer, and lifestyle factors like extensive consumption of tobacco, betel quid, and alcohol are the major etiological factors of oral cancer. Treatment of oral cancer includes surgery, radiation therapy, and chemotherapy, but this treatment possesses lots of side effects. Therefore, scientists and medical experts are utilizing natural products and medicinal plants for new drug development. Natural products and phytochemicals showed better efficacy with less toxicity. However, most of the phytochemicals showed poor permeability and less bioavailability. To combat this problem, scientists developed nanosized nanoemulsions of phytochemicals to treat various ailments. Nanoemulsions of phytochemicals exhibited better efficacy than their free form due to increased permeability and bioavailability. Numerous phytopharmaceuticals have been formulated for nanoemulsions to date and tested for their anticancer potential against various cancers, including oral cancer and oral health management.

AbstractLeishmaniasis is a complex disease caused by different species of genus Leishmania, which affects millions of people spanning over 88 countries causing extensive mortality and morbidity. Leishmaniasis exists in three clinical forms; cutaneous, mucocutaneous and visceral. Anti-leishmanial therapy is one of the challenging fields due to the presence of wide range of Leishmania species and host response against the pathogenic infection. Clinical survey reveals toxicity of drugs and trial compounds causing death among patients and predominant resistance to different class of antimonials among the leishmaniasis patient. Identification of appropriate target protein is a primary and important phase of drug development and Leishmania is a suitable system for targeted drug development as it branched out quite early from the higher eukaryotes like human. With the advancement of genomic era and availability of whole genome sequences of Leishmania species, relevant information on their respective genes and proteins are now easily extracted. Hence, in the current study, to aid the targeted drug therapy, an exhaustive whole genome scale comparative sequence analysis was performed to identify genes/proteins exclusive to Leishmania. Subsequently, further filtration was employed to identify the individual Leishmania species specific gene/proteins. Among such proteins, a considerable number was found to have no recognizable structure and functions. Hence, efforts were taken to characterize these Leishmania exclusive gene/proteins via providing additional sequence, structure, localization and functional information. All the information about each of these Leishmania exclusive gene/proteins from five different Leishmania species has been systemically categorized and represented in the form a user-friendly database called Leish-ExP, which is freely available at http://www.hpppi.iicb.res.in/Leish-ex.

This study aimed to investigate a method to manage antimicrobial resistance (AMR) issues by exploring soil microorganisms that are capable of producing bioactive compounds. Eight different types of soil were selected from three locations to screen, isolate, and identify microorganisms that are capable of producing antimicrobial compounds. The multi-drug resistant strains are Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Candida albicans were selected for primary and secondary screening using the crowded plate method and the agar well diffusion method. Inhibition zones were measured, and data were assessed using statistical tests to check for normality and differences between parametric variables and nonparametric data. This was followed by biochemical characterization, DNA isolation, and polymerase chain reaction (PCR). Molecular identification was performed using 16S rRNA amplification and sequencing. Here, 86 isolates containing bacteria and fungi were successfully extracted from soil samples. Further, 49 of 86 microbes showed possible antimicrobial activity, but only 12 isolates resulted in distinct inhibition zones with the selected multi-drug resistant strains. The following different taxa were identified: Firmicutes (nine strains), Proteobacteria (one strain), Actinobacteria (one strain), and Azotobacter (one strain). Species are represented in a phylogenetic tree, which was constructed using the unweighted pair-group method with arithmetic mean (UPGMA) method. The evolutionary distances were computed using the Maximum Composite Likelihood method. The identified microorganisms showed antimicrobial activity, confirming that soil microorganisms have great potential to address AMR issues.

Otilonium bromide is a poorly absorbed oral medication used to control irritable bowel syndrome. It is thought to act as a muscle relaxant in the intestine. Here we show that otilonium bromide has broad-spectrum antibacterial and antifungal activity, including against multi-drug resistant strains. Our results suggest otilonium bromide could act on enteric pathogens and may offer a new scaffold for poorly absorbed intestinal antimicrobial therapy.

Marine organisms represent a new extensive source for bioactive molecules. They have the potential to provide new therapeutic alternatives to treat human diseases. In this paper, we describe and discuss a variety of isolated and semisynthetic molecules obtained from marine sources. These compounds are in phase II, phase III and at the commercialization stage of new drug development. A description of the mechanism of action, dosage used and side effects are also reported. The positive results obtained from these studies have triggered the development of new studies to evaluate the prospects for utilization of marine organisms.

Antimicrobial Evaluation

Abstract series of 2-(p-substituted phenyl)-5-(2-{4-[(p-chloro-fluorophenyl)=phenyl] piperazin-1-yl}- acetamido)-benzoxazoles were synthesized and tested for their antimicrobial activities. The structures of the new derivatives were elucidated by spectral techniques. The minimum inhibitory concentrations (MIC) of the new benzoxazoles, along with those of previously synthesized analogues, were determined against standard bacterial and fungal strains and drug-resistant isolates, and compared with those of several reference drugs. The new benzoxazole derivatives were found to possess a broad spectrum of antimicrobial activity with MIC values of 32 - 1024 μg/ml. Although the standard drugs were more active against the tested pathogens, the activities of the new benzoxazoles and the reference drugs were largely similar against the drug-resistant isolates.

New Drug Development

New drugs are mostly obtained from Natural sources. The traditional and ethic medicines have provided evidence on the therapeutic properties and resulted in some distinguished drug discovery of natural products. The microorganisms and the endogenous active materials from human or animal have also become a significant approach to the discovery of a drug. Bioinformatics and artificial intelligence have facilitated the study and development of products. For discovery of natural products different software have been used. Different computational software needed in the future for the predicting features in new drug development, for instance pharmacokinetic and pharmacodynamics, in drug development lead positive impact. This review focus on natural product drug discovery and uses innovative strategies and techniques as a part of discovery of drugs from natural products.
