Cinnoline or Benzo-pyridazine has its place in the family of fairly well-known benzfuseddiazine heterocycles. Because of its natural occurrence and synthetic exploration, cinnoline compounds validated its thought-provoking bioactivity through a number of research publications and patents during last few decades. A creative consideration has been rewarded to the synthesis of cinnoline based heterocyclic compounds, mostly due to their wide range of diverse pharmacological activities. The present review covers the principle approaches to the synthesis of cinnoline nucleus and almost all biological properties of 115 cinnoline derivatives reported during the last 65 years from natural and synthetic origin with 140 references.

AbstractBetulinic acid is a naturally occurring pentacyclic lupane-type triterpenoid usually isolated from birch trees, but present in many other botanical sources. It is found in different plant organs, both as a free aglycon and as glycosyl derivatives. A wide range of pharmacological activities has been described for this triterpenoid, including antiviral and antitumor effects. In addition, several other interesting properties have been identified in the fields of immunity and metabolism, namely antidiabetic, antihyperlipidemic, and anti-inflammatory activities. Taken together, these latter three properties make betulinic acid a highly interesting prospect for treating metabolic syndrome. The present review focuses on the therapeutic potential of this agent, along with several of its semisynthetic derivatives, which could open new frontiers in the use of natural product-based medicines.

A large number of heterocyclic compounds with five membered rings as the parent nucleus such as tetrazoles, imidazoles, triazoles, oxadiazoles, thiadiazoles, thiazoles, etc. have been studied extensively owing to their fascinating biological properties like anticancer, antifungal, antimicrobial, antitumor, anticonvulsant, antiviral, etc. 1,2,3-Triazoles are important class of five-membered biologically active heterocyclic compounds as they exhibit wide range of pharmacological activities. Triazoles are of two types viz. 1,2,3-triazole and 1,2,4-triazole. These compounds have drawn great attention from chemists and biologists since their discovery. In recent years, triazoles has emerged as an interesting field in drug design for many researchers due to their enormous pharmacological scope. The present review aims to sum up the medicinal significance of 1,2,3-triazoles as one of the most significant structures for the development of drug molecules like anticancer, antibacterial, HIV protease inhibitors, antifungal, anti-inflammatory (COX-1/COX-2 inhibitors), antiprotozoal, anticonvulsant, antioxidant and others, which are under clinical trials. Various benzyl and benzyl-halide functionalized 1,2,3-triazole derivatives like rufinamide, mubritinib (TAK-165) and suvorexant showing excellent biological activities have been used as medicine. In present review, more stress has been laid on the major developments in the therapeutic aspects of triazole pharmacophore for the last two decades.

Nitrogen-containing heterocycles are one of the most common structural motifs in approximately 80% of the marketed drugs. Of these, benzimidazoles analogues are known to elicit a wide spectrum of pharmaceutical activities such as anticancer, antibacterial, antiparasitic, antiviral, antifungal as well as chemosensor effect. Based on the benzimidazole core fused heterocyclic compounds, crescent-shaped bisbenzimidazoles were developed which provided an early breakthrough in the sequence-specific DNA recognition. Over the years, a number of functional variations in the bisbenzimidazole core have led to the emergence of their unique properties and established them as versatile ligands against several classes of pathogens. The present review provides an overview of diverse pharmacological activities of the bisbenzimidazole analogues in the past decade with a brief account of its development through the years.

Bioactive Potential

AbstractBiomaterials have had an increasingly important role in recent decades, in biomedical device design and the development of tissue engineering solutions for cell delivery, drug delivery, device integration, tissue replacement, and more. There is an increasing trend in tissue engineering to use natural substrates, such as macromolecules native to plants and animals to improve the biocompatibility and biodegradability of delivered materials. At the same time, these materials have favourable mechanical properties and often considered to be biologically inert. More importantly, these macromolecules possess innate functions and properties due to their unique chemical composition and structure, which increase their bioactivity and therapeutic potential in a wide range of applications. While much focus has been on integrating these materials into these devices via a spectrum of cross-linking mechanisms, little attention is drawn to residual bioactivity that is often hampered during isolation, purification, and production processes. Herein, we discuss methods of initial material characterisation to determine innate bioactivity, means of material processing including cross-linking, decellularisation, and purification techniques and finally, a biological assessment of retained bioactivity of a final product. This review aims to address considerations for biomaterials design from natural polymers, through the optimisation and preservation of bioactive components that maximise the inherent bioactive potency of the substrate to promote tissue regeneration.

In this review we systematized the theoretical and experimental data concerning the versatile approaches for the synthesis of N-acylphenothiazines. The aim of the study was to compile the literature reported worldwide in the past 20 years. This article also reviewed the analysis of pharmacological activities of these heterocycles as one of the promising chemotherapeutic objects for the modern bioorganic and medicinal chemistry. It has been hypothesized that the enormous biological potential of these moieties is due to the radical nature in the acyl moiety. Therefore, the present review will be a good contribution to the literature and will provide the platform for the medicinal chemistry researchers to carry out more studies aiming the N-acylphenothiazine moieties as the novel chemotherapeutic agents.
