[PMID: 37716415 DOI: 10.1016/j.bmcl.2023.129484] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Revised: 09/01/2023] [Accepted: 09/11/2023] [Indexed: 09/18/2023]
Abstract
Hypoxia in cancer is important in the development of cancer-selective medicines. Here, a novel hypoxia-responsible dual-prodrug is described. We designed and synthesized 2-nitroimidazole derivatives which spontaneously release both a PYG inhibitor and gemcitabine under hypoxic conditions. One such derivative, a prodrug 9 was found to be stable against chemical and enzymatic hydrolysis, and upon chemical reduction of the nitro group on imidazole, successfully releases both drugs. In an in vitro proliferation assay using human pancreatic cells, compound 9 exhibited significant anti-proliferative effects in hypoxia but fewer effects in normoxia. Consequently, prodrug 9 should be useful for cancer treatment due to its improved cancer selectivity and potential to overcome drug resistance.

Abstract
Peptides and proteins are involved in almost all biological events. In this review, three chemical biology tools, which were developed for peptide/protein sciences from a viewpoint of peptide/amide bond cleavage, are overviewed. First, study on an artificial amino acid that enables stimulus-responsive functional control of peptides/proteins is briefly described. Two N-S acyl transfer reaction-based tools, one a linker molecule for facile identification of target proteins of bioactive compounds and the other a reagent for selective labeling of proteins of interest, are then discussed.

Abstract
Just after receiving my Ph.D. degree in 2004 from Tokushima University, under the supervision of Professor Masayuki Shibuya, I had the opportunity to work as a Research Associate in the laboratory of Professor Kim D. Janda at The Scripps Research Institute in the U.S., for about a year. Since it has already been more than 10 years since my time at Scripps, the specific research performed at that time may no longer be of interest to readers, but the benefit of working in a different research environment is timeless. Therefore, this paper describes not only details of the research conducted, but also the significance of working in a foreign country as a postdoc, and the subsequent influence those experiences at The Scripps Research Institute have had on my career.

Abstract
Amide bonds are the most prevalent structures found in organic molecules and various biomolecules such as peptides, proteins, DNA, and RNA. The unique feature of amide bonds is their ability to form resonating structures, thus, they are highly stable and adopt particular three-dimensional structures, which, in turn, are responsible for their functions. The main focus of this review article is to report the methodologies for the activation of the unactivated amide bonds present in biomolecules, which includes the enzymatic approach, metal complexes, and non-metal based methods. This article also discusses some of the applications of amide bond activation approaches in the sequencing of proteins and the synthesis of peptide acids, esters, amides, and thioesters.

Abstract
Trimethyl lock (TML) systems are based on ortho-hydroxydihydrocinnamic acid derivatives displaying increased lactonization reactivity owing to unfavorable steric interactions of three pendant methyl groups, and this leads to the formation of hydrocoumarins. Protection of the phenolic hydroxy function or masking of the reactivity as benzoquinone derivatives prevents lactonization and provides a trigger for controlled release of molecules attached to the carboxylic acid function through amides, esters, or thioesters. Their easy synthesis and possible chemical adaption to several different triggers make TML a highly versatile module for the development of drug-delivery systems, prodrug approaches, cell-imaging tools, molecular tools for supramolecular chemistry, as well as smart stimuliresponsive materials.

Abstract
Elucidation of biological functions of peptides and proteins is essential for understanding peptide/protein-related biological events and developing drugs. Caged peptides and proteins that release a parent active peptide/protein by photo-irradiation have successfully been employed to elucidate the functions. Whereas the usual caged peptide/protein enables conversion of an inactive form to an active form (OFF-to-ON conversion) by photo-induced deprotection, photo-triggered main chain cleavage is reported to be applicable to ON-to-OFF conversion. These peptides and proteins are photo-responsive; however, if peptides and proteins could respond to other stimuli such as disease-related environment or enzymes, their range of application should be widened. To convert the photo-responsive peptide/protein into other stimulus-responsive peptide/protein, quite laborious de novo design and synthesis of the stimulus-responsive unit are required. In this context, we designed a stimulus-responsive peptide-bond-cleaving residue (Spr) in which the stimuli available for the main chain cleavage vary according to the choice of protecting groups on the residue. In this review, design and synthesis of Spr are introduced, and challenges to apply Spr to other fields to enable, for example, functional control, localization control, delivery of cargos, labeling of a protein of interest in living cells, and identification of target proteins of bioactive ligands are discussed.

Abstract
Stimulus-responsive biomolecules are attractive targets to understand biomolecule behaviour as well as to explore their therapeutic and diagnostic applications. We demonstrate that a reduction-responsive cleavable group (chemically caged unit) introduced into the guanine ring enables modulation of the secondary structure transition of an oligonucleotide in a reduction-responsive and traceless manner leaving the unmodified oligonucleotide of interest. This simple but robust strategy could yield a variety of stimuli-responsive oligonucleotides.

Spontaneously hyperactive MEK-Erk pathway mediates paradoxical facilitation of cell proliferation in mild hypoxia. Biochim Biophys Acta Gen Subj 2014; 1850:640-6.

Abstract
BACKGROUND Oxygen is important for common eukaryotic cells to generate ATP. Pathophysiological conditions such as ischemic diseases cause tissue hypoxia. In addition, oxygen availability in deep tissues is supposed to be far lower than surrounding atmosphere even in healthy animals, and the oxygen partial pressures in most normal tissues are estimated to be around 40-50mmHg, so-called mild hypoxia. Recent studies have demonstrated that mild hypoxia has distinct effects on living cells from severe hypoxia. For instance, mild hypoxia was reported to promote cell reprogramming. Although severe hypoxia is known to inhibit cell proliferation, mild hypoxia has been paradoxically demonstrated to increase cell proliferation. However, it has not been clarified by which molecular mechanisms mild hypoxia evokes the discontinuous increment of cell proliferation. METHODS We established experimental conditions showing the opposite influences of mild and severe hypoxia on cell proliferation using undifferentiated Caco2 human colon carcinoma cells in order to clarify the underlying molecular mechanism. RESULTS The basal activity of Erk, which is a typical mediator of mitogenic signals, is spontaneously increased specifically in cells exposed to mild hypoxia, and inhibition of MEK, an upstream kinase of the Erk, completely inhibited the mild hypoxia-induced enhancement of cell proliferation. CONCLUSIONS Spontaneous hyperactivation of the MEK-Erk pathway by mild hypoxia should be the plausible molecular mechanism of the paradoxical promotion of cell proliferation. GENERAL SIGNIFICANCE Our findings will provide clues to the molecular basis of mild hypoxia-evoked phenomena such as cell reprogramming.

Abstract
The increased resistance of hypoxic cells to all forms of cancer therapy presents a major barrier to the successful treatment of most solid tumors. Inhibition of the essential kinase Checkpoint kinase 1 (Chk1) has been described as a promising cancer therapy for tumors with high levels of hypoxia-induced replication stress. However, as inhibition of Chk1 affects normal replication and induces DNA damage, these agents also have the potential to induce genomic instability and contribute to tumorigenesis. To overcome this problem, we have developed a bioreductive prodrug, which functions as a Chk1/Aurora A inhibitor specifically in hypoxic conditions. To achieve this activity, a key functionality on the Chk1 inhibitor (CH-01) is masked by a bioreductive group, rendering the compound inactive as a Chk1/Aurora A inhibitor. Reduction of the bioreductive group nitro moiety, under hypoxic conditions, reveals an electron-donating substituent that leads to fragmentation of the molecule, affording the active inhibitor. Most importantly, we show a significant loss of viability in cancer cell lines exposed to hypoxia in the presence of CH-01. This novel approach targets the most aggressive and therapy-resistant tumor fraction while protecting normal tissue from therapy-induced genomic instability.

Abstract
An understanding of the physiological significance of peptides and proteins is indispensable in the fields of life sciences and drug development. Recently, methods for controlling peptide and protein activities using stimuli such as UV irradiation have been attracting much attention because of their potential for clarifying the physiological roles of the peptides/proteins. In this context, we have developed a stimulus-responsive amino acid that induces peptide-bond cleavage after exposure to a stimulus. Although it has previously been reported that stimulus-responsive units can respond to a specific stimulus, our stimulus-responsive amino acid is potentially applicable to any stimulus simply by changing the protective group. In this review, the design and synthesis of stimulus-responsive amino acids are described. Their applications in chemical biology, including their use for spatiotemporal control of the activity of peptides in living cells, are also reported.
