Aliphatic thiols are in high demand materials chemistry. Herein, a synthesis of thio-derivatives 1-hexene vinylidene dimer is described. The approach, based on hydroalumination reaction with further replacement the organoaluminum function sulfur using thiourea or dimethyl disulfide, provides anti-Markovnikov products, 2-butyloctane-1-thiol 5-(methylsulfanylmethyl)undecane, moderate yields. phos...

Thiol-bearing microgels have been synthesised from copolymerisation of 2-(acetylthio)ethylacrylate and 2-hydroxyethylmethacrylate, and subsequent deprotection using sodium thiomethoxide. The concentration of thiol groups on these microgels could be tailored by use of different molar ratios of the two monomers. These thiol-bearing microgels were shown to adhere to ex vivo porcine urinary bladder...

Thiol-ene photo-click hydrogels were prepared via step-growth polymerisation using thiol-functionalised type-I collagen and 8-arm poly(ethylene glycol) norbornene-terminated (PEG-NB), as a potential injectable regenerative device. Type-I collagen was thiol-functionalised by a ring opening reaction with 2-iminothiolane (2IT), whereby up to 80 Abs. % functionalisation and 90 RPN% triple helical p...

The title compound, [Fe(4)(C(6)H(6)NS)(CH(3)S)S(CO)(11)], com-prises two butterfly-shaped sub-cluster cores, Fe(2)S(2)N and Fe(2)S(2), joined together by a spiro-type μ(4)-S atom. The (pyridin-2-yl)methane-thiol-ate ligand is attached to the Fe(2)(CO)(5) unit in a μ-κN:κ(2)S mode, and the methane-thiol-ate ligand is coordinated to the Fe(2)(CO)(6) unit in a μ-κ(2)S fashion.

Intra-chain thiol ester bonds are present in a limited number of proteins. The thiol ester class of proteins includes vertebrate alpha 2-macroglobulin and the complement proteins C3 and C4. We report here the first instance of a thiol ester protein from an invertebrate, the alpha 2-macroglobulin proteinase-inhibitor homologue present in the plasma of the American horseshoe crab Limulus polyphem...

Abstract A series of new quinazoline-4(3H)-one derivatives (2-16) have been synthesized using methyl α-[(4-oxoquinazolin-2-yl)thio]acetate (1) as precursor. The corresponding hydrazide (2) and thiosemicarbazide (4) were from this ester via the reaction with hydrazine hydrate ammonium thiocyanate respectively. was employed to synthesize 2-amino-1,3,4-thiadiazole (5) 1,3,4-triazole-5-thiol (6) it...

Cannabidiol, the major nonpsychotropic phytocannabinoid, has been recently demonstrated to induce apoptosis in primary lymphocytes via an oxidative stress-dependent mechanism. Cannabidiol can be converted by microsomal enzymes to the hydroxyquinone metabolite HU-331 that forms adducts with glutathione. The present study tested the hypothesis that HU-331 could cause apoptosis via the depletion o...
