Simple construction and manipulation of low-molecular-weight supramolecular nanogels, based on the introduction of multiple hydrogen bonding interactions, with the desired physical properties to achieve effective and safe delivery of drugs for cancer therapy remain highly challenging. Herein, a novel supramolecular oligomer cytosine (Cy)-polypropylene glycol containing self-complementary multiple hydrogen-bonded Cy moieties is developed, which undergoes spontaneous self-assembly to form nanosized particles in an aqueous environment...

Drug levels in patients' bloodstreams vary among individuals and consequently therapeutic drug monitoring (TDM) is fundamental to controlling the effective therapeutic range. For TDM purposes, different analytical approaches have been used, mainly based on immunoassay, liquid chromatography- ultraviolet, liquid chromatography-mass spectrometry and liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods. More recently a matrix-assisted laser desorption/ionisation method has been proposed for the determination of irinotecan levels in the plasma of subjects under therapy and this method has been cross- validated by comparison with data achieved by LC-MS/MS...

REVIEW
Sumeet Gupta, Vikas Jhawat
Conventional approaches of drug discovery are very complex, costly and time consuming. But after the completion of human genome project, applications of pharmacogenomics in this area completely revolutionize the drug discovery and development process to produce a quality by design (QbD) approach based products. The applications of two areas of pharmacogenomics i.e. structural and functional pharmacogenomics excel the drug discovery process by employing genomic data in drug target identification and evaluation, lead optimization via high throughput screening, evaluation of drug metabolizing enzymes, drug transporters and drug receptors using computer aided technique and bioinformatics library data base...

BACKGROUND: Nuclear factor-kappaB (NF-kappaB) has been reported to regulate various genes involved in cancer and inflammation. Accordingly, drugs inhibiting NF-kappaB may possess both anti-inflammatory and anticancer properties. So there is a need to discover novel compounds which should not only be a potential lead but also less toxic and cost effective. OBJECTIVES: The aim of the study was to develop new synthetic anti-inflammatory and cytotoxic agents targeting NF-kappaB...

The current anticancer and antileishmanial drug arsenal presents several limitations concerning their specificity, efficacy, costs and the emergence of drug-resistant cells lines, which encourages the urgent need to search for new alternatives. Inspired by the fact that gold(I)-based compounds are promising antitumoral and antileishmanial drug candidates, we synthesized novel gold(I) complexes containing phosphine and 5-phenyl-1,3,4-oxadiazole-2-thione and evaluated their anticancer and antileishmanial activities...

Genetic variations in cancer cells are the underpinning for the development of resistance and failure of the treatment by current anticancer drugs. Thus, an ideal drug must overcome failure of treatment and prevents development of drug resistance. There are a wide variety of emerging, easy to prepare and cost effective group of drugs that are collectively called peptoids or peptidomimetics. These new set of drugs exhibit distinct features including protease resistance, are non-immunogenic, do not hinder functionality and backbone polarity, and can adopt different conformations...

BACKGROUND: Computer-based technology is becoming increasingly essential in biological research where drug discovery programs start with the identification of suitable drug targets. 2-Methoxyestradiol (2ME2) is a 17β-estradiol metabolite that induces apoptosis in various cancer cell lines including cervical cancer, breast cancer and multiple myeloma. Owing to 2ME2's poor in vivo bioavailability, our laboratory in silico-designed and subsequently synthesized a novel 2ME2 analogue, 2-ethyl-3-O-sulphamoyl-estra-1,3,5(10),15-tetraen-17-ol (ESE-15-ol), using receptor- and ligand molecular modeling...

BACKGROUND: Cancer is one of the leading cause of mortality. Even though efficient drugs are being produced to treat cancer, conventional medicines are costly and have adverse effects. As a result, alternative treatments are being tried due to their low cost and little or no adverse effects. Our previous study identified one such alternative in rice callus suspension culture (RCSC) which was more efficient than Taxol® and Etoposide, in reducing the viability of human colon and renal cancer cells in culture with minimal or no effect on a normal cell line...

Bispecific antibodies (BsAbs), capable of directing T cells to kill specific cancer cells by transiently binding the two cell types, have emerged as one class of promising cancer immunotherapies. However, their wide clinical application might be hampered by two deficiencies: high cost and inconvenience in drug administration. We present concept-proving data that these problems could be bypassed by using an enhanced nonviral DNA vector minicircle (MC) to produce BsAb in vivo. We found that the anti-CD3/CD20 produced from the minicircle (MC...

Molecular Hybridization is an approach in rational drug design where new chemical entities are obtained by combining two or more pharmacophoric units from different bioactive compounds into a single molecule. Through this approach, medicinal chemists hope that the new hybrid derivative presents: better affinity and efficacy when compared to the parent drugs; a modified selectivity profile with improvement over pharmacokinetic and pharmacodynamic restrictions; dual or multiple modes of action; reduction of undesirable side effects; decreases in drug-drug interactions; reduced emergence or spread of drug resistance in microorganisms and protozoans; and lower cost...

PURPOSE OF REVIEW: The purpose of this review is to provide a practical clinical approach to confusion in the patient with cancer. Confusion in the cancer population has a broader differential diagnosis than in the general medical population. The clinician must consider the usual differential diagnoses as well as causes unique to the cancer patient including direct complications from the cancer and indirect complications related to cancer treatment. RECENT FINDINGS: In the recent age of precision medicine, the oncologist now utilizes the genomic profile of both the patient and the tumor to provide advanced biologic therapies including targeted anticancer drugs, antiangiogenic agents, and immunotherapy...

Formation of the G-quadruplex in the human telomeric DNA is an effective way to inhibit telomerase activity. Therefore, screening ligands of G-quadruplex has potential applications in the treatment of cancer by inhibit telomerase activity. Although several techniques have been explored for screening of telomeric G-quadruplexes ligands, high-throughput screening method for fast screening telomere-binding ligands from the large compound library is still urgently needed. Herein, a label-free fluorescence strategy has been proposed for high-throughput screening telomere-binding ligands by using DNA-copper nanoparticles (DNA-CuNPs) as a signal probe...

BACKGROUND AND PURPOSE: Deciphering chemical mechanism-of-action (MoA) enables the development of novel therapeutics (e.g. drug repositioning) and evaluation of drug side effects. Development of novel computational methods for chemical MoA assessment under systems pharmacology framework would accelerate drug discovery and development with high efficiency and low cost. EXPERIMENTAL APPROACH: In this study, we proposed an improved network-based inference method, namely balanced substructure-drug-target network-based inference (bSDTNBI), to predict MoA for old drugs, clinical failed drugs, and new chemical entities...

Medico-economic evaluations estimate, for a given health technology, the added cost and the clinical benefit compared to a reference strategy. The objective here is to analyze the criteria used to measure clinical benefit as the basis for market access and reimbursement decisions for drugs in oncology both in France and in Europe. Prolonged overall survival is the criterion of choice to demonstrate the benefit of an anticancer drug; a survival gain of 2 to 3 months or more would be considered as relevant for a new product versus the comparator...

One of fundamental challenges in cancer studies is that varying molecular characteristics of different tumor types may lead to resistance to certain drugs. As a result, the same drug can lead to significantly different results in different types of cancer thus emphasizing the need for individualized medicine. Individual prediction of drug response has great potential to aid in improving the clinical outcome and reduce the financial costs associated with prescribing chemotherapy drugs to which the patient's tumor might be resistant...

Spending on anticancer drugs has risen rapidly over the past two decades. A key policy question is whether new anticancer drugs offer value, given their high cost. Using data from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database, we assessed the value of new cancer treatments in routine clinical practice for patients with metastatic breast, lung, or kidney cancer or chronic myeloid leukemia in the periods 1996-2000 and 2007-11. We found that there were large increases in medical costs, but also large gains in life expectancy...

Medicinal inorganic chemistry plays an important role in exploring the properties of metal ions for the designing of new drugs. The field has been stimulated by the success of cis-platin, the worldbest selling anticancer drug and platinum complexes with reduced toxicity, oral activity and activity against resistant tumors are currently on clinical trial. The use of cis-platin is, however, severely limited by its toxic side-effects. This has stimulated chemists to employ different strategies in the development of new metal-based anticancer agents with different mechanisms of action...
