Recent advances in the discovery of small molecules targeting glioblastoma

Glioblastoma (GBM) is one of the most common central nervous system cancers. It is characterized as a fast-growing tumor that arises from multiple cell types with neural stem-cell-like properties. Additionally, GBM tumors are highly invasive, which is attributed to the presence of glioblastoma stem cells that makes surgery ineffective in most cases. Currently, temozolomide is the unique chemotherapy option approved by the U.S. Food and Drug Administration for GBM treatment. This review analyzes the emergence and development of new synthetic small molecules discovered as promising anti-glioblastoma agents. A number of compounds were described herein and grouped according to the main chemical class used in the drug discovery process. Importantly, we focused only on synthetic compounds published in the last 10 years, thus excluding natural products. Furthermore, we included in this review only those most biologically active compounds with proven in vitro and/or in vivo efficacy.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of Thiazolidin-2-one, you can also check out more blogs about2682-49-7

Synthesis of aryl-heteroaryl ureas (AHUs) based on 4-aminoquinoline and their evaluation against the insulin-like growth factor receptor (IGF-1R)

The insulin-like growth factor receptor (IGF-1R) is a receptor tyrosine kinase (RTK) involved in all stages of the development and propagation of breast and other cancers. The inhibition of IGF-1R by small molecules remains a promising strategy to treat cancer. Herein, we explore SAR around previously characterized lead compound (1), which is an aryl-heteroaryl urea (AHU) consisting of 4-aminoquinaldine and a substituted aromatic ring system. A library of novel AHU compounds was prepared based on derivatives of the 4-aminoquinoline heterocycle (including various 2-substituted derivatives, and naphthyridines). The compounds were screened for in vitro inhibitory activity against IGF-1R, and several compounds with improved activity (3-5 muM) were identified. Furthermore, a computational docking study was performed, which identifies a fairly consistent lowest energy mode of binding for the more-active set of inhibitors in this series, while the less-active inhibitors do not adopt a consistent mode of binding.

Synthesis and antibacterial screening of some 2-(p-substituted benzylidene)-3-(5-propyl-1, 3, 4-thiadiazol-2-yl) thiazolidin-4-ones

A series of 2-(p-substituted benzylidene)-3-(5-propyl-1, 3, 4-thiadiazol-2-yl) thiazolidin-4-ones were synthesized by the reaction of Schiff’s bases of N-(p-substituted benzylidene)-5 propyl -1, 3, 4-thiadiazole-2-amines with thioglycolic acid in 1, 4-dioxane as solvent and studied for their in vitro antibacterial activity. Reaction of thiosemicarbazide with butanoic acid in presence of concentrated sulphuric acid led to the formation of 5-propyl-1, 3, 4-thiadiazole-2-amines which on further reaction with different p-substituted benzaldehydes yielded the compounds Schiff’s bases of N-(p-substituted benzylidene)-5-propyl -1,3, 4-thiadiazole-2-amines which is further reaction with thioglycollic acid in presence of small amount of zinc chloride in 1,4 dioxane as solvent gave title compounds.

Inverse electron demand diels-alder (IEDDA) reactions: Synthesis of heterocycles and natural products along with bioorthogonal and material sciences applications

In this review we chose to concentrate on the bibliography data from 2013 to 2015 (until February), related to the application of the Inverse Electron Demand Diels-Alder (IEDDA) reaction to the synthesis of heterocycles, as building blocks for natural products Moreover, the application of the IEDDA reaction to the recently developed bioorthogonal ligations (in 2008), using tetrazines moieties as the diene partners, and engineered alkenes or alkynes as dienophiles, will be detailed. The in vivo applications of the bioorthogonal liga-tions are particularly amazing and undoubtedly demonstrate the usefulness of this chemistry.

The zebrafish Kupffer’s vesicle as a model system for the molecular mechanisms by which the lack of Polycystin-2 leads to stimulation of CFTR

In autosomal dominant polycystic kidney disease (ADPKD), cyst inflation and continuous enlargement are associated with marked transepithelial ion and fluid secretion into the cyst lumen via cystic fibrosis transmembrane conductance regulator (CFTR). Indeed, the inhibition or degradation of CFTR prevents the fluid accumulation within cysts. The in vivo mechanisms by which the lack of Polycystin-2 leads to CFTR stimulation are an outstanding challenge in ADPKD research and may bring important biomarkers for the disease. However, hampering their study, the available ADPKD in vitro cellular models lack the three-dimensional architecture of renal cysts and the ADPKD mouse models offer limited access for liveimaging experiments in embryonic kidneys. Here, we tested the zebrafish Kupffer’s vesicle (KV) as an alternative model-organ. KV is a fluid-filled vesicular organ, lined by epithelial cells that express both CFTR and Polycystin-2 endogenously, being each of them easily knocked-down. Our data on the intracellular distribution of Polycystin-2 support its involvement in the KV fluid-flow induced Ca2+ -signalling. Mirroring kidney cysts, the KV lumen inflation is dependent on CFTR activity and, as we clearly show, the knockdown of Polycystin-2 results in larger KV lumens through overstimulation of CFTR. In conclusion, we propose the zebrafish KV as a model organ to study the renal cyst inflation. Favouring its use, KV volume can be easily determined by in vivo imaging offering a live readout for screening compounds and genes that may prevent cyst enlargement through CFTR inhibition.

NEW SYNTHESES OF 2-CYANO-1-METHYL-3-<2-<<(5-METHYL-1H-IMIDAZOL-4-YL)METHYL>THIO>ETHYL>GUANIDINE (CIMETIDINE)

A new synthesis of 2-cyano-1-methyl-3-<2-<<(5-methyl-1-H-imidazol-4-yl)methyl>thio>ethyl>guanidine, 6 (cimetidine) utilizing the aziridine derivative 5 as a two-carbon one-nitrogen synthon, is reported.Attempts to prepare the key intermediate 5 via aziridine forming ring closure of 18, as well as attempted insertion of aziridine into the carbon-sulphur bond in 11 or 12 are described.Low yields of 6 were obtained both on insertion of aziridine within 12, and on alkylation of 14 with 8, followed by decomposition of the sulphonium salt 15.Formation of 5 from 2 and aziridine in the presence of Ag(I) ions is found to follow predominantly an elimination-addition mechanism, via the highly unstable carbodiimide 4, rather than direct substitution.
