    A Systematic Role of Metabolomics, Metabolic Pathways, and Chemical Metabolism in Lung Cancer
    (MDPI, 2023-02-08T00:00:00) Kannampuzha, Sandra; Mukherjee, Anirban Goutam; Wanjari, Uddesh Ramesh; Gopalakrishnan, Abilash Valsala; Murali, Reshma; Namachivayam, Arunraj; Renu, Kaviyarasi; Dey, Abhijit; Vellingiri, Balachandar; Madhyastha, Harishkumar; Ganesan, Raja
    Lung cancer (LC) is considered as one of the leading causes of cancer-associated mortalities. Cancer cells� reprogrammed metabolism results in changes in metabolite concentrations, which can be utilized to identify a distinct metabolic pattern or fingerprint for cancer detection or diagnosis. By detecting different metabolic variations in the expression levels of LC patients, this will help and enhance early diagnosis methods as well as new treatment strategies. The majority of patients are identified at advanced stages after undergoing a number of surgical procedures or diagnostic testing, including the invasive procedures. This could be overcome by understanding the mechanism and function of differently regulated metabolites. Significant variations in the metabolites present in the different samples can be analyzed and used as early biomarkers. They could also be used to analyze the specific progression and type as well as stages of cancer type making it easier for the treatment process. The main aim of this review article is to focus on rewired metabolic pathways and the associated metabolite alterations that can be used as diagnostic and therapeutic targets in lung cancer diagnosis as well as treatment strategies. � 2023 by the authors.

    A Perspective on Medicinal Chemistry Approaches for Targeting Pyruvate Kinase M2
    (American Chemical Society, 2021-11-02T00:00:00) Arora, Sahil; Joshi, Gaurav; Chaturvedi, Anuhar; Heuser, Michael; Patil, Santoshkumar; Kumar, Raj
    The allosteric regulation of pyruvate kinase M2 (PKM2) affects the switching of the PKM2 protein between the high-activity and low-activity states that allow ATP and lactate production, respectively. PKM2, in its low catalytic state (dimeric form), is chiefly active in metabolically energetic cells, including cancer cells. More recently, PKM2 has emerged as an attractive target due to its role in metabolic dysfunction and other interrelated conditions. PKM2 (dimer) activity can be inhibited by modulating PKM2 dimer�tetramer dynamics using either PKM2 inhibitors that bind at the ATP binding active site of PKM2 (dimer) or PKM2 activators that bind at the allosteric site of PKM2, thus activating PKM2 from the dimer formation to the tetrameric formation. The present perspective focuses on medicinal chemistry approaches to design and discover PKM2 inhibitors and activators and further provides a scope for the future design of compounds targeting PKM2 with better efficacy and selectivity. � 2021 American Chemical Society
