Abstract
Glutamine transporters are integral to the metabolism of glutamine in both healthy tissues and cancerous cells, playing a pivotal role in maintaining amino acid balance, synthesizing biomolecules, and regulating redox equilibrium. Their critical functions in cellular metabolism make them promising targets for oncological therapies. Recent years have witnessed substantial progress in the field of glutamine transporters, marked by breakthroughs in understanding of their protein structures and the discovery of novel inhibitors, prodrugs, and radiotracers. This review provides a comprehensive update on the latest advancements in modulators targeting the glutamine transporter, with special attention given to LAT1 and ASCT2. It also discusses innovative approaches in drug design aimed at these transporters.

Abstract
Biologically equivalent replacements of key moieties in molecules rationalize scaffold hopping, patent busting, or R-group enumeration. Yet, this information may depend upon the expert-defined space, and might be subjective and biased toward the chemistries they get used to. Most importantly, these practices are often informatively incomplete since they are often compromised by a try-and-error cycle, and although they depict what kind of substructures are suitable for the replacement occurrence, they fail to explain the driving forces to support such interchanges. The protein data bank (PDB) encodes a receptor-ligand interaction pattern and could be an optional source to mine structural surrogates. However, manual decoding of PDB has become almost impossible and redundant to excavate the bioisosteric know-how. Therefore, a text parsing workflow has been developed to automatically extract the local structural replacement of a specific structure from PDB by finding spatial and steric interaction overlaps between the fragments in endogenous ligands and particular ligand fragments. Taking the glycosyl domain for instance, a total of 49 520 replacements that overlap on nucleotide ribose were identified and categorized based on their SMILE codes. A predominately ring system, such as aliphatic and aromatic rings, was observed; yet, amide and sulfonamide replacements also occur. We believe these findings may enlighten medicinal chemists on the structure design and optimization of ligands using the bioisosteric replacement strategy.

Abstract
Albumin has emerged as a versatile drug carrier. To harness albumin as a carrier for doxorubicin (DOX), we synthesized three acid-labile DOX prodrugs using stearic acid (SA), oleic acid (OA), and linoleic acid (LA) as the albumin-binding motif, respectively. Different from conventional albumin nanodrugs (such as Abraxane, with a drug loading of 10%), the DOX prodrugs assembled albumin nanoparticles (NPs) have an ultrahigh drug loading (>35%). Noteworthy, we demonstrated that the saturation of fatty acids exerted great influence on colloidal stability of prodrug NPs, thus affecting their in vivo pharmacokinetics, tumor accumulation and antitumor efficacy. Furthermore, the hydrazone bond-bridged DOX prodrugs could remain intact in the bloodstream but allow DOX to be released in the acidic tumor environment, resulting in improved antitumor efficacy and safety. Our work gives novel insights into the structure-to-efficacy relationship of albumin-bound fatty acid prodrugs and provides a simple strategy for advanced albumin-bound nanomedicines.

Abstract
The naturally occurring linear dipeptide JBP923 (trans-4-l-Hyp-l-Ser, HS-tLL) with anti-inflammatory effects showed potential for the treatment of inflammatory bowel disease (IBD). However, colon-specific delivery after oral administration is still a challenge because its absorption is mediated by oligopeptide transporter 1 (PEPT1) in the upper small intestine and because of its instability in the gastrointestinal tract. Therefore, we aimed to enhance the colon-targeting efficiency by modulating HS-tLL chirality to synthesize eight enantiomers. Among these enantiomers, trans-4-d-Hyp-d-Ser, cis-4-l-Hyp-d-Ser, cis-4-d-Hyp-l-Ser, and cis-4-d-Hyp-d-Ser did not work as substrates of PEPT1 and were stable in the gastrointestinal tract, resulting in enhanced colonic accumulation through the paracellular pathway due to the loose tight junctions in IBD. Interestingly, cis-4-d-Hyp-d-Ser exerted the most potent therapeutic effect on IBD. Our findings revealed the impact of chirality on the colonic accumulation of the linear dipeptide, providing strategies for the colon-targeted delivery of the linear dipeptide for the treatment of IBD.

Bioorg Med Chem Lett 2020; 33:127728. [PMID: 33346010 DOI: 10.1016/j.bmcl.2020.127728] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Revised: 11/28/2020] [Accepted: 12/01/2020] [Indexed: 12/14/2022]
Abstract
Triptolide (TP) is a diterpene epoxide component extracted from Tripterygium wilfordii and has been shown to possess an impressive anticancer effect. However, TP has not yet entered any clinic trials due to the severe adverse effects that resulted from the off-target absorption and distribution found in animal studies. In this study, we designed and synthesized three amino acids (tryptophan, valine, and lysine) based TP prodrugs to target ATB0,+ which are highly expressed in pancreatic cancer cells for more effective pancreatic cancer therapy. The stability, uptake profiles, uptake mechanism, and cancer-killing ability were studied in vitro. All three prodrugs showed increased uptake and enhanced cytotoxicity in pancreatic cancer cells, but not in normal pancreatic cells. The difference in killing effect on normal and cancer cells was attributed to pancreatic cancer over-expressed ATB0,+-mediated uptake. Specifically, tryptophan-conjugated TP prodrug (TP-Trp) showed the highest uptake and the best cancer cell killing effect, considered as the best candidate. The present study provided the proof-of-concept of exploiting TP prodrug to target ATB0,+ for pancreatic cancer-selective delivery and treatment.
