Abstract
In this research work, a series of 16 quinazoline derivatives bearing ibuprofen and an amino acid were designed as inhibitors of epidermal growth factor receptor tyrosine kinase domain (EGFR-TKD) and cyclooxygenase-2 (COX-2) with the intention of presenting dual action in their biological behavior. The designed compounds were synthesized and assessed for cytotoxicity on epithelial cancer cells lines (AGS, A-431, MCF-7, MDA-MB-231) and epithelial non-tumorigenic cell line (HaCaT). From this evaluation, derivative 6 was observed to exhibit higher cytotoxic potency (IC50) than gefitinib (reference drug) on three cancer cell lines (0.034 μM in A-431, 2.67 μM in MCF-7, and 3.64 μM in AGS) without showing activity on the non-tumorigenic cell line (>100 μM). Furthermore, assessment of EGFR-TKD inhibition by 6 showed a discreet difference compared to gefitinib. Additionally, 6 was used to conduct an in vivo anti-inflammatory assay using the 12-O-tetradecanoylphorbol-3-acetate (TPA) method, and it was shown to be 5 times more potent than ibuprofen. Molecular dynamics studies of EGFR-TKD revealed interactions between compound 6 and M793. On the other hand, one significant interaction was observed for COX-2, involving S531. The RMSD graph indicated that the ligand remained stable in 50 ns.

Abstract
The delivery of a drug to a specific organ or tissue at an efficacious concentration is the pharmacokinetic (PK) hallmark of promoting effective pharmacological action at a target site with an acceptable safety profile. Sub-optimal pharmaceutical or ADME profiles of drug candidates, which can often be a function of inherently poor physicochemical properties, pose significant challenges to drug discovery and development teams and may contribute to high compound attrition rates. Medicinal chemists have exploited prodrugs as an informed strategy to productively enhance the profiles of new chemical entities by optimizing the physicochemical, biopharmaceutical, and pharmacokinetic properties as well as selectively delivering a molecule to the site of action as a means of addressing a range of limitations. While discovery scientists have traditionally employed prodrugs to improve solubility and membrane permeability, the growing sophistication of prodrug technologies has enabled a significant expansion of their scope and applications as an empowering tool to mitigate a broad range of drug delivery challenges. Prodrugs have emerged as successful solutions to resolve non-linear exposure, inadequate exposure to support toxicological studies, pH-dependent absorption, high pill burden, formulation challenges, lack of feasibility of developing solid and liquid dosage forms, first-pass metabolism, high dosing frequency translating to reduced patient compliance and poor site-specific drug delivery. During the period 2012-2022, the US Food and Drug Administration (FDA) approved 50 prodrugs, which amounts to 13% of approved small molecule drugs, reflecting both the importance and success of implementing prodrug approaches in the pursuit of developing safe and effective drugs to address unmet medical needs.

Abstract
Camptothecin (CPT) and its derivatives are potent candidates for cancer treatment. However, the clinical applications are largely restricted by non-selectivity and severe toxicities. The peptide transporter 1 (PEPT1), which is highly expressed in human intestines, has been found to be overexpressed in several cancer cells. This discovery suggests that PEPT1 has the potential to serve as a therapeutic target for both improving bioavailability and cancer-targeting treatment. Therefore, a prodrug approach for CPT targeting at PEPT1 highly expressed cancer cells was adopted in the present study. Eighteen CPT prodrugs, its peptidic conjugates, were synthesized and the structures were confirmed by NMR and HRMS. The protein expression profiles of PEPT1 in different cell lines were performed using immunofluorescence assay and western blotting analysis. The cytotoxicity of CPT prodrugs and their uptake via competition with Gly-Sar, a typical substrate of PEPT1, were evaluated in both PEPT1-overexpressed and under expressed cells. The results demonstrated that most CPT prodrugs significantly impaired Gly-Sar uptake, suggesting a higher affinity of CPT-peptidic conjugates for PEPT1 and PEPT1 overexpression cells. In addition, these prodrugs demonstrated a higher capability for inhibiting cell growth in PEPT1 highly-expressed cancer cells compared to PEPT1 under expressed cells. These results indicated that this peptidic prodrug strategy might offer great potential for improved tumor selectivity and chemotherapeutic efficacy of CPT.

Abstract
The clinical utility of gemcitabine, an antimetabolite antineoplastic agent applied in various chemotherapy treatments, is limited due to the required intravenous injection. Although chemical structure modifications of gemcitabine result in enhanced oral bioavailability, these modifications compromise complex synthetic routes and cause unexpected side effects. In this study, gemcitabine-loaded glycocholic acid-modified micelles (Gem-PPG) were prepared for enhanced oral chemotherapy. The in vitro transport pathway experiments revealed that intact Gem-PPG were transported across the intestinal epithelial monolayer via an apical sodium-dependent bile acid transporter (ASBT)-mediated pathway. In mice, the pharmacokinetic analyses demonstrated that the oral bioavailability of Gem-PPG approached 81%, compared to less than 20% for unmodified micelles. In addition, the antitumor activity of oral Gem-PPG (30 mg/kg, BIW) was superior to that of free drug injection (60 mg/kg, BIW) in the xenograft model. Moreover, the assessments of hematology, blood chemistry, and histology all indicated the hypotoxicity profile of the drug-loaded micelles.

Abstract
Fmoc-dipeptides are a class of short aromatic peptides featuring eminent supramolecular self-assembly, which is due to the aromaticity of the Fmoc group, which improves the association of peptide building blocks. This study aimed to introduce a new dipeptide hydrogel scaffold, Fmoc-phenylalanine-valine (Fmoc-FV), for 3D culture of various cells. Peptide hydrogel scaffolds were prepared by the pH-titration method in various concentrations and temperatures, and characterized by spectroscopic methods, including circular dichroism, attenuated total reflection FT-IR and fluorimetry. Mechanical behaviors such as thixotropy and temperature-sensitivity were investigated by oscillatory rheology. The Fmoc-FV hydrogels were then applied in 3D-culture of WJ-MSCs (mesenchymal stem cells), HUVECs (normal endothelial cells), and MDA-MB231 (tumor cell line) by live-dead fluorescence microscopy and Alamar blue viability assay experiments. The results confirmed that the β-sheet structure is principally interlocked by π-π stacking of the Fmoc groups and entangled nanofibrous morphologies as revealed by FE-SEM. Fmoc-FV self-assembly in physiologic conditions resulted in a thermo-sensitive and shear-thinning hydrogel. Notably, the Fmoc-FV hydrogel exhibited cell type-dependent biological activity, so higher cell proliferation was attained in HUVEC or MDA-MB231 cells than WJ-MSCs, indicating a possible need for incorporating cell-adhesion ligands in the Fmoc-FV hydrogel matrix. Therefore, the structural and biological properties of the Fmoc-dipeptide hydrogels are inter-related and can affect their applications in 3D cell culture and regenerative medicine.

Abstract
Gemcitabine is an intravenously administered anti-cancer nucleoside analogue. Systemic exposure following oral administration of gemcitabine is limited by extensive first-pass metabolism via cytidine deaminase (CDA) and potentially by saturation of nucleoside transporter-mediated intestinal uptake. An amino acid ester prodrug of gemcitabine, 5'-l-valyl-gemcitabine (V-Gem), was previously shown to be a substrate of the intestinally expressed peptide transporter 1 (PEPT1) and stable against CDA-mediated metabolism. However, preliminary studies did not evaluate the in vivo oral performance of V-Gem as compared to parent drug. In the present study, we evaluated the pharmacokinetics and in vivo oral absorption of gemcitabine and V-Gem following intravenous and oral administrations in mice. These studies revealed that V-Gem undergoes rapid systemic elimination (half-life < 1 min) and has a low oral bioavailability (<1%). Most importantly, the systemic exposure of gemcitabine was not different following oral administration of equimolar doses of gemcitabine (gemcitabine bioavailability of 18.3%) and V-Gem (gemcitabine bioavailability of 16.7%). Single-pass intestinal perfusions with portal blood sampling in mice revealed that V-Gem undergoes extensive activation in intestinal epithelial cells and that gemcitabine undergoes first-pass metabolism in intestinal epithelial cells. Thus, formulation of gemcitabine as the prodrug V-Gem does not increase systemic gemcitabine exposure following oral dosing, due, in part, to the instability of V-Gem in intestinal epithelial cells.

Abstract
Gemcitabine is an anticancer drug used to treat a wide range of solid tumors and is a first line treatment for pancreatic cancer. Our group has previously developed novel conjugates of gemcitabine with cell-penetrating peptides (CPP), and here we report some preliminary data regarding the pharmacokinetics of gemcitabine, two gemcitabine-CPP conjugates and respective CPP gathered from GastroPlus™, and analyze these results considering our previous evaluation of gemcitabine release and conjugates’ bioactivity. Additionally, seeking to shed some light on the relation between the penetration ability of CPP and their physicochemical properties, chemical descriptors for the 20 natural amino acids were calculated, a new principal property scale (z-scale) was created and CPP prediction models were developed, establishing quantitative structure-activity relationships (QSAR). The z-scores of the peptides conjugated with gemcitabine are presented and analyzed with the aforementioned data.

Abstract
Improving the bioavailability and tumor-targeting ability of a prodrug, as well as monitoring its active ingredient release in vivo, is still a challenge in cancer diagnosis and therapy. Herein, a specific nanomized tumor-microenvironment-active near-infrared (NIR) fluorescent DCM-S-GEM/PEG prodrug was developed as a potent monitoring platform, wherein we conjugated antitumor drug gemcitabine (GEM) and NIR fluorescent chromophore dicyanomethylene-4H-pyran (DCM) via glutathione (GSH)-activatable disulfide linker and encapsulated DCM-S-GEM into an amphiphilic polymer DSPE-mPEG by self-assembly. The nanomized DCM-S-GEM/PEG prodrug exhibits excellent photostability and high biocompatibility, significantly improving the therapeutic efficacy toward lung tumor cells with fewer side-effects toward normal cells. Furthermore, when compared with the standalone DCM-S-GEM prodrug, the micellization with diblock DSPE-mPEG avoids fast metabolism, facilitates the accumulation of drugs in lung tumor tissues, displays longer tumor retention, and realizes precise drug release in lung tumors. The nanomized DCM-S-GEM/PEG prodrug can be developed as a promising tool to monitor prodrug delivery and activation processes in vivo.

Abstract
The coupling of gemcitabine with functionalized carboxylic acids using peptide coupling conditions afforded 4-N-alkanoyl analogues with a terminal alkyne or azido moiety. Reaction of 4-N-tosylgemcitabine with azidoalkyl amine provided 4-N-alkyl gemcitabine with a terminal azido group. Click reaction with silane building blocks afforded 4-N-alkanoyl or 4-N-alkyl gemcitabine analogues suitable for fluorination. RP-HPLC analysis indicated better chemical stability of 4-N-alkyl gemcitabine analogues versus 4-N-alkanoyl analogues in acidic aqueous conditions. The 4-N-alkanoyl gemcitabine analogues showed potent cytostatic activity against L1210 cell line, but cytotoxicity of the 4-N-alkylgemcitabine analogues was low. However, 4-N-alkanoyl and 4-N-alkyl analogues had comparable antiproliferative activities in the HEK293 cells. The 4-N-alkyl analogue with a terminal azide group was shown to be localized inside HEK293 cells by fluorescence microscopy after labelling with Fluor 488-alkyne. The [18F]4-N-alkyl or alkanoyl silane gemcitabine analogues were successfully synthesized using microscale and conventional silane-labeling radiochemical protocols. Preliminary positron-emission tomography (PET) imaging in mice showed the biodistribution of [18F]4-N-alkyl to have initial concentration in the liver, kidneys and GI tract followed by increasing signal in the bone.
