Abstract
αvβ3 integrins play an important role in angiogenesis and cell migration in cancer and are highly expressed on the activated endothelial cells of newly formed blood vessels. Here, we compare the targeting characteristics of 4 68Ga-labeled multimeric cyclic arginine-glycine-aspartate (RGD)-based tracers in an αvβ3 integrin-expressing tumor model and a tumor model in which αvβ3 integrin is expressed solely on the neovasculature. Methods: Female BALB/c nude mice were subcutaneously injected with SK-RC-52 (αvβ3 integrin-positive) or FaDu (αvβ3 integrin-negative) tumor cells. 68Ga-labeled DOTA-(RGD)2, TRAP-(RGD)3, FSC-(RGD)3, or THP-(RGD)3 was intravenously administered to the mice (0.5 nmol per mouse, 10-20 MBq), followed by small-animal PET/CT imaging and ex vivo biodistribution studies 1 h after injection. Nonspecific uptake of the tracers in both models was determined by coinjecting an excess of unlabeled DOTA-(RGD)2 (50 nmol) along with the radiolabeled tracers. Results: Imaging and biodistribution data showed specific uptake in the tumors for each tracer in both models. Tumor uptake of 68Ga-FSC-(RGD)3 was significantly higher than that of 68Ga-DOTA-(RGD)2, 68Ga-TRAP-(RGD)3, or 68Ga-THP-(RGD)3 in the SK-RC-52 model but not in the FaDu model, in which 68Ga-FSC-(RGD)3 showed significantly higher tumor uptake than 68Ga-TRAP-(RGD)3 Most importantly, differences were also observed in normal tissues and in tumor-to-blood ratios. Conclusion: All tracers showed sufficient targeting of αvβ3 integrin expression to allow for tumor detection. Although the highest tumor uptake was found for 68Ga-FSC-(RGD)3 and 68Ga-THP-(RGD)3 in the SK-RC-52 and FaDu models, respectively, selection of the optimal tracer for specific diagnostic applications also depends on tumor-to-blood ratio and uptake in normal tissues; these factors should therefore also be considered.

Antibodies (Basel) 2018; 7:E16.

Abstract
Antibody-Drug Conjugates (ADCs) have been through multiple cycles of technological innovation since the concept was first practically demonstrated ~40 years ago. Current technology is focusing on large, whole immunoglobulin formats (of which there are approaching 100 in clinical development), many with site-specifically conjugated payloads numbering 2 or 4. Despite the success of trastuzumab-emtansine in breast cancer, ADCs have generally failed to have an impact in solid tumours, leading many to explore alternative, smaller formats which have better penetrating properties as well as more rapid pharmacokinetics (PK). This review describes research and development progress over the last ~10 years obtained from the primary literature or conferences covering over a dozen different smaller format-drug conjugates from 80 kDa to around 1 kDa in total size. In general, these agents are potent in vitro, particularly more recent ones incorporating ultra-potent payloads such as auristatins or maytansinoids, but this potency profile changes when testing in vivo due to the more rapid clearance. Strategies to manipulate the PK properties, whilst retaining the more effective tumour penetrating properties could at last make small-format drug conjugates viable alternative therapeutics to the more established ADCs.

Abstract
Aim: Alkylating agents and antimetabolites are cytotoxic drugs commonly used in cancer treatment. These medications are often associated with serious side effects on normal tissues and organs. Methodology: To improve the pharmacological profile of the alkylating agent POPAM and the antimetabolite 5-fluorouracil, novel integrin-targeted delivery systems based on c(RGDyK) were successfully synthesized. The new conjugates were tested in vitro against different cancer cells such as PC3, SKOV3, A549, MCF7 and MBA-MB-321. Results & conclusion: The c(RGDyK) conjugates of POPAM demonstrated better inhibitory effects and selectivity compared with c(RGDyK) and POPAM. The c(RGDyK) conjugates of 5-FUA demonstrated diverse inhibitory effects compared with c(RGDyK) and 5-FUA related to the levels of integrin expression, the conjugate stability and sensitivity of cancer cells to 5-FUA.

Abstract
Preclinical Research Doxorubicin (DOX) is commonly used for the treatment of breast cancer and lymphoma. However, its clinical use has been severely limited due to cardiotoxicity, requiring the development of safer and more efficient pharmaceutical formulations of DOX. Advances in nanotechnology have provided new ways to administer chemotherapeutic drugs like DOX are conveyed into the body and to tumor sites. These Nanotechnology approaches have aided in the selective accumulation of DOX into tumor sites via the enhanced permeability and retention. However, the absence of active targeting ligands still hinders the effective delivery of DOX. Among all active targeting ligands developed to date, RGD peptide (Arginylglycylaspartic acid) occupies a unique position owing to its inherent safety, biocompatibility, and targeting ability. Accordingly, modification of DOX with RGD ligand is anticipated to improve transport of DOX into tumor cells. In this review, we discuss using RGD peptide for improving the therapeutic efficacy of DOX nanomedicine. Drug Dev Res 78 : 283-291, 2017. © 2017 Wiley Periodicals, Inc.

Abstract
Alterations in integrin expression and function promote tumour growth, invasion, metastasis and neoangiogenesis. Head and neck cancers are highly vascular tumours with a tendency to metastasise. They express a wide range of integrin receptors. Expression of the αv and β1 subunits has been explored relatively extensively and linked to tumour progression and metastasis. Individual receptors αvβ3 and αvβ5 have proved popular targets for diagnostic and therapeutic agents but lesser studied receptors, such as αvβ6, αvβ8, and β1 subfamily members, also show promise. This review presents the current knowledge of integrin expression and function in squamous cell carcinoma of the head and neck (HNSCC), with a particular focus on the arginine-glycine-aspartate (RGD)-binding integrins, in order to highlight the potential of integrins as targets for personalised tumour-specific identification and therapy.
