Advances in the design, discovery, and optimization of aurora kinase inhibitors as anticancer agents

INTRODUCTION

Aurora kinases (AKs) play key roles during carcinogenesis and show a close relationship with many cellular effects including mitotic entry, spindle assembly and chromosomal alignment biorientation. Indeed, elevated levels of AKs have been reported in several different tumor types, leading research scientists to investigate ways that we can target AKs for the purpose of developing new anticancer therapeutics.

Anticancer potential and structure activity studies of purine and pyrimidine derivatives: an updated review

Cancer is the world's leading cause of death impacting millions of lives globally. The increasing research over the past several decades has focused on the development of new anticancer drugs, but still cancer continues to be a global health challenge. Thus, several new alternative therapeutic strategies have been tried for the drug design and discovery. Purine and pyrimidine heterocyclic compounds have received attention recently due to their potential in targeting various cancers. It is evident from the recently published data over the last decade that incorporation of the purine and pyrimidine rings in the synthesized derivatives resulted in the development of potent anticancer molecules. This review presents synthetic strategies encompassing several examples of recently developed purine and pyrimidine-containing compounds as anticancer agents. In addition, their structure-activity relationships are represented in the schemes indicating the fragment or groups that are essential for the enhanced anticancer activities. Purine and pyrimidines combined with other heterocyclic compounds have resulted in many novel anticancer molecules that address the challenges of drug resistance. The purine and pyrimidine derivatives showed significantly enhanced anticancer activities against targeted receptor proteins with numerous compounds with an IC50 value in the nanomolar range. The review will support medicinal chemists and contribute in progression and development of synthesis of more potent chemotherapeutic drug candidates to mitigate the burden of this dreadful disease.

Recent advances in the synthesis, reaction, and bio-evaluation potential of purines as precursor pharmacophores in chemical reactions: a review

Purines are nitrogenous heterocyclic compounds characterized by the presence of two fused rings: pyrimidine and imidazole. Their significance is underscored by their widespread occurrence in natural products as the metabolic processes of all living organisms heavily rely on purines and their synthetic derivatives. Furthermore, purines exhibit considerable bioactivity, highlighting their importance in biological systems. Given their unique structural characteristics and ability to yield a diverse array of bioactive molecules, purines have attracted substantial attention from researchers. This review illustrates the recent methods for the synthesis of purines from diaminomaleonitrile, urea derivatives, imidazole, and pyrimidine derivatives reported from 2019 to 2024. Additionally, it elucidates the various chemical modifications applied to the purine nucleus, including benzoylation, alkylation, halogenation, amination, selenylation, thiolation, condensation, diazotization, coupling reactions, and other miscellaneous reactions. Moreover, this review discusses several biological evaluations, including the mechanisms of action of purine derivatives as anticancer, antimicrobial, anti-inflammatory, antiviral, antioxidant, and anti-Alzheimer agents. This review aims to assist researchers in synthetic organic and medicinal chemistry toward the development and enhancement of novel methodologies for the synthesis of new purine molecules while supporting biologists in the identification of new targets for bio-evaluation.

Caffeine and Purine Derivatives: A Comprehensive Review on the Chemistry, Biosynthetic Pathways, Synthesis-Related Reactions, Biomedical Prospectives and Clinical Applications

Caffeine and purine derivatives represent interesting chemical moieties, which show various biological activities. Caffeine is an alkaloid that belongs to the family of methylxanthine alkaloids and it is present in food, beverages, and drugs. Coffee, tea, and some other beverages are a major source of caffeine in the human diet. Caffeine can be extracted from tea or coffee using hot water with dichloromethane or chloroform and the leftover is known as decaffeinated coffee or tea. Caffeine and its derivatives were synthesized via different procedures on small and large scales. It competitively antagonizes the adenosine receptors (ARs), which are G protein-coupled receptors largely distributed in the human body, including the heart, vessels, brain, and kidneys. Recently, many reports showed the effect of caffeine derivatives in the treatment of many diseases such as Alzheimer's, asthma, parkinsonism, and cancer. Also, it is used as an antioxidant, anti-inflammatory, analgesic, and hypocholesterolemic agent. The present review article discusses the synthesis, reactivity, and biological and pharmacological properties of caffeine and its derivatives. The biosynthesis and biotransformation of caffeine in coffee and tea leaves and the human body were summarized in the review.

Aurora Kinase B Inhibition: A Potential Therapeutic Strategy for Cancer

Aurora kinase B (AURKB) is a mitotic serine/threonine protein kinase that belongs to the aurora kinase family along with aurora kinase A (AURKA) and aurora kinase C (AURKC). AURKB is a member of the chromosomal passenger protein complex and plays a role in cell cycle progression. Deregulation of AURKB is observed in several tumors and its overexpression is frequently linked to tumor cell invasion, metastasis and drug resistance. AURKB has emerged as an attractive drug target leading to the development of small molecule inhibitors. This review summarizes recent findings pertaining to the role of AURKB in tumor development, therapy related drug resistance, and its inhibition as a potential therapeutic strategy for cancer. We discuss AURKB inhibitors that are in preclinical and clinical development and combination studies of AURKB inhibition with other therapeutic strategies.
