1, 3-thiazolidin-4-one derivatives bearing pyrimidine moieties: Design, computational studies, synthesis, characterization, antimicrobial, MTT assessment and molecular docking assessment

1, 3-thiazolidin-4-one derivatives bearing 5,6-dihydrothieno[2,3-d]pyrimidine moiety (1-10) were designed and assessed for the level of bioactivity, computationally. Computational findings revealed that compounds 1-8 were exhibiting very good bioactivity score as GPCR ligand, and lying in the zone for active drug molecule, while compounds 9-10, were lying under the zone of moderately active drug molecule. The bioactive compounds (1-10) were then synthesized, characterized and assessed for antimicrobial potential and percent viability of cells. All the compounds (1-10) were found to have very good antimicrobial potential, although some of the members of the series possessed better antimicrobial potential than the reference drug ?Ciprofloxacin?. In Addition, molecular docking assessment was carried out for all the synthesized compounds against the protein GlcN-6-P-synthase to embed both in-silico and in vitro results. The findings revealed that most of the compounds were found to exhibit significant hydrogen bonding to the residues of GlcN-6-P-synthase with a binding affinity -6.9 to -5.3 Kcal/mole. The compounds were also tested for percent viability of cells by MTT assay, and the results revealed that ? 90 % viability of the cells was found @ 3.12 muM and ? 70 @ 100 muM.

1,3-thiazolidin-4-ones: Biological potential, history, synthetic development and green methodologies

Background: We present here the synthesis of 1,3-thiazolidin-4-one (1) and its functionalised analogues, such as the classical isosteres, glitazone (1,3-thiazolidine-2,4-dione) (2), rhodanine (2-thioxo-1,3-thiazolidin-4-one) (3) and pseudothiohydantoin (2-imino-1,3-thiazolidin-4-one) (4) started in the midnineteenth century to the present day (1865-2018). Objective: The review focuses on the differences in the representation of the molecular structures discussed here over time since the first discussions about the structural theory by Kekule, Couper and Butlerov. Moreover, advanced synthesis methodologies have been developed for obtaining these functional group, including green chemistry. We discuss about its structure and stability and we show the great biological potential. Conclusion: The 1,3-thiazolidin-4-one nucleus and functionalised analogues such as glitazones (1,3thiazolidine-2,4-diones), rhodanines (2-thioxo-1,3-thiazolidin-4-ones) and pseudothiohydantoins (2-imino-1,3thiazolidine-2-4-ones) have great pharmacological importance, and they are already found in commercial pharmaceuticals. Studies indicate a promising future in the area of medicinal chemistry with potential activities against different diseases. The synthesis of these nuclei started in the mid-nineteenth century (1865), with the first discussions about the structural theory by Kekule, Couper and Butlerov. The present study has demonstrated the differences in the representations of the molecular structures discussed here over time. Since then, various synthetic methodologies have been developed for obtaining these nuclei, and several studies on their structural and biological properties have been performed. Different studies with regards to the green synthesis of these compounds were also presented here. This is the result of the process of environmental awareness. Additionally, the planet Earth is already showing clear signs of depletion, which is currently decreasing the quality of life.

Methotrexate prodrugs sensitive to reactive oxygen species for the improved treatment of rheumatoid arthritis

Methotrexate (MTX) is the standard of care in the treatment of rheumatoid arthritis (RA), a common autoimmune disease that is characterized by chronic inflammation in the synovial membrane of joints. Unfortunately, MTX suffers from high discontinuation rates due to a large variability in efficacy and, in particular, adverse effects. As inflammation is associated with elevated levels of reactive oxygen species (ROS) like H2O2, we propose to improve treatment through site-selective delivery of MTX to inflammatory tissue by use of a H2O2 sensitive MTX prodrug. To establish proof proof-of-concept, two novel H2O2 sensitive, thiazolidinone-based MTX prodrugs were synthesized and evaluated for this purpose. MTX-gamma-thiazolidinone (MTX-gamma-TZ) exhibited the most promising properties ? good to high chemical and metabolic stability, excellent aqueous solubility, while being activated when subjected to patho-physiological concentrations of H2O2. In vivo, MTX-gamma-TZ exhibited comparable efficacy to MTX in a murine collagen type II-induced arthritis (CIA) model while treated mice showed indications of reduced toxicity as their body weight decreased less towards the end of the study, compared to the MTX-treated group.

Selective glutathione repletion with oral oxothiazolidine carboxylate (OTZ) in the radiated tumor-bearing rat

Oxothiazolidine carboxylate (OTZ) is a cysteine prodrug which augments intracellular glutathione (GSH) levels. We examined the effects of oral OTZ on tumor and host tissue reduced GSH levels in fasting and radiated models of GSH depletion. In addition, we studied the tumor’s ability to utilize OTZ via the enzyme, oxoprolinase. Fischer 344 rats (n = 40) were implanted with MCA sarcoma and studied at 10% tumor burden. Treatment consisted of 10 mmol/kg OTZ or buffer orally. After a 24-hr fast, 16 animals were treated and tumor, kidney, jejunal, and colonic mucosa were collected after 4 hr. Significant increases in GSH with OTZ (n = 8) vs buffer (n = 8) were seen in kidney (5.6 ¡À 0.4 vs 4.3 ¡À 0.9; P < 0.01), jejunum (13.8 ¡À 1.3 vs 12.1 ¡À 1.1; P < 0.05), and colon (6.7 ¡À 1.2 vs 5.3 ¡À 0.6; P < 0.05), but not tumor (8.9 ¡À 2.4 vs 10.6 ¡À 1.4; P = 0.12). Sixteen animals were treated 4 hr before and 18 hr following 1100 cGy of abdominal radiation and at 4 days, tumor, jejunal, and colonic mucosa were collected. Significant increases in GSH with OTZ (n = 8) vs buffer (n = 8) were noted in jejunum (9.3 ¡À 1.1 vs 7.5 ¡À 1.8; P < 0.05) and colon (5.6 ¡À 1.1 vs 4.3 ¡À 0.9; P < 0.05) but not tumor (8.4 ¡À 1.6 vs 7.6 ¡À 1.4; P = 0.34). To determine tissue oxoprolinase activity, tumor, kidney, liver, jejunal, and colonic mucosa were collected from 8 animals. Oxoprolinase activity was highest in the kidney (814 ¡À 145) with no difference noted between liver and tumor (280 ¡À 117 and 324 ¡À 137, respectively). Oral OTZ selectively increases reduced GSH levels in normal tissues compared to tumor following fasting and whole abdominal radiation. This increase does not appear to be due to a differential activity of oxoprolinase. OTZ may have a role in protection against toxicity associated with oxidative injury by selective repletion of normal host tissue GSH levels.

Latest research on synthetics compounds with antileishmanial activity

Leishmaniasis is a neglected tropical disease caused by around 20 species of obligate intramacrophage protozoa of the genus Leishmania. This disease is an important cause of morbidity and mortality that primarily impacts the poorest populations living in tropical and sub-tropical regions of the world, but has become of concern in some developed countries. The resistance of leishmanial parasites to the drugs available and their undesirable side effects have prompted the discovery of new synthetic compounds with potent antileishmanial activity and fewer side effects that can serve as new therapeutic agents. In this article, we make a comprehensive review of the most recent advances of synthetic compounds with antileishmanial activity (from 2015 to the early 2017). Furthermore, we covered the structure- activity relationship studies that allow for optimization and selection of the most promising drugs, and the biochemical mechanisms that explain the antileishmanial activities observed.

Design, synthesis and evaluation of Coumarin-Phenylthiazole conjugates as cholinesterase inhibitors

In this paper, we report the design, synthesis, in-silico, and in-vitro evaluations of a series of coumarin-phenylthiazole conjugates to inhibit cholinesterase enzymes. The coumarin and phenylthiazole derivatives have been synthesized separately, and further combined through covalent amine bond linkage. The synthesized compounds showed more inhibition towards BuChE than AChE, where 4-(3-bromophenyl)-1,3-thiazol-2-amine (7i) exhibited the strongest inhibition against BuChE with an IC50 value of 3.54 muM. For the conjugates, 3-[2-[4-(3-nitrophenyl)thiazol-2-ylamino]acetyl]chromen-2-one (8j) exhibited strongest inhibition with an IC50 value of 46.47 muM. The better inhibition activities towards BuChE are also shown by 3-bromo and 2-fluoro derivatives. It was also observed that the substitution at 3-position, on phenylthiazole moiety produced better results against BuChE than 4-substituted counterparts.
