Less stress: We compare three structurally different classes of histone deacetylase (HDAC) inhibitors that contain benzamide, hydroxamate, or thiol groups as the zinc binding group (ZBG) for their ability to protect cortical neurons in culture from cell death induced by oxidative stress. Novel benzamide-based ligands selectively inhibit HDAC3 but provide no neuroprotection in the HCA-cortical neuron model of oxidative stress. We compare three structurally different classes of histone deacetylase (HDAC) inhibitors that contain benzamide, hydroxamate, or thiol groups as the zinc binding group (ZBG) for their ability to protect cortical neurons in culture from cell death induced by oxidative stress. This study reveals that none of the benzamide-based HDAC inhibitors (HDACIs) provides any neuroprotection whatsoever, in distinct contrast to HDACIs that contain other ZBGs. Some of the sulfur-containing HDACIs, namely the thiols, thioesters, and disulfides present modest neuroprotective activity but show toxicity at higher concentrations Taken together, these data demonstrate that the HDAC6-selective mercaptoacetamides that were reported previously provide the best protection in the homocysteic acid model of oxidative stress, thus further supporting their study in animal models of neurodegenerative diseases.

Environmentally benign and biodegradable lactic acid was identified as alternative solvent and catalyst for the tandem one-pot synthesis of Hantzsch 2-aminothiazole derivatives from readily available aralkyl ketones through in-situ regioselective α-bromination using N-bromosuccinimide followed by heterocyclization using thiourea at 90-100°. The major advantages of the present method include short reaction times (10-15 min), practical, simple to perform, easy work-up, good yield of products (up to 96%), productive for large-scale applications, free from apply of α-bromoketones (lachrymator) as substrates, avoids column purification Hence, the present method met with the concepts of both Wender’s “”ideal synthesis”” and sustainable chem. process.

Akbarzadeh, Elaheh; Shockravi, Abbas; Vatanpour, Vahid published the artcile< Efficient thiazole-based polyimines as selective and reversible chemical absorbents for CO2 capture and separation: Synthesis, characterization and application>, Computed Properties of 57493-24-0, the main research area is thiazole thioether polyimine chem absorbent carbon dioxide capture separation.

A new series of polyimines (PIMs-1-9) including ortho-linked thiazole units and flexible thioether linkages were synthesized from diamine monomers (DA-1-3) and some com. available aromatic dialdehydes (terephthalaldehyde, isophthalaldehyde and 2,5-thiophenedicarboxaldehyde) via Schiff-base condensation reaction. The synthesized polymers as amorphous solids were obtained with high efficiency (74-89%), inherent viscosities in the range of 0.98-1.33 dL g-1 in DMF and high solubility in aprotic polar solvents (DMSO, DMAc, DMF, NMP, and Py). The PIMs were characterized via viscosimetry, elemental anal., FT-IR spectroscopy, X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), thermogravimetric anal. (TGA) and differential scanning calorimetry (DSC). High thermal resistance revealed for PIMs as glass transition temperatures (Tgs) ranging in 104-189 °C along with 10% weight loss temperatures exceeding 268-390 °C in air and 310-430 °C in nitrogen atm. The polymers were examined for CO2 absorption at 298 K as well as 318 K and high absorption capacity exhibited (maximum 3.72 mmol/g or 163.68 mg/g at 1 bar and 298 K for PIM-4) after 2 h and desorption at 373 K under vacuum conditions (100 mbar) in 20 min. More importantly, remarkable ideal selectivity ratios of CO2/N2 (77.3) and CO2/CH4 (13.7) at 1 bar and 298 K were obtained and recyclability of PIM-4 for CO2 capturing was determined without considerable loss of gas absorption.
