Dermal penetration enhancers were evaluated (14) using diffusion cell techniques, hairless mouse skin and hydrocortisone as the model drug. The following were synthesized: 1-dodecanoylpiperidine (1), 1-dodecanoylpyrrolidine (2), 1-dodecanoyl-2-piperidinone (3), 1-dodecanoyl-2-pyrrolidinone (4), 2-decylcyclohexanone (5), 2-decylcyclopentanone (6), 4-(dodecanoyl)-thiomorpholine (7), N,N-didodecylacetamide (8) and N-dodecyltricyclo [3.3.1.1(3,7)]decane-1-carboxamide (11). N-Acetylcaprolactam (9), 4-acetylmorpholine (10) and N-dodecylpyrrolidinone (13) were purchased. The syntheses of Azone, N-(1-oxododecyl)morpholine (12) and N-dodecyl-2-piperidinone (14) have been reported previously. Enhancers were applied at 0.4 M in propylene glycol (PG) (or as a suspension) to mouse skin. Hydrocortisone (0.03 M in PG) was applied 1 h following enhancer treatment. Controls (no pretreatment) yielded 24 h diffusion cell receptor concentrations (Q(24)) of 9.93 +/- 3.15 mu M and model drug skin retention of 26.1 +/- 5.6 mu g g(-1). Compound 7 yielded a high Q(24) of 208.18 +/- 39.52 mu M. The highest skin retention was observed with 6 of 566.7 +/- 39.7 mu g g(-1). Azone gave values of 218.96 +/- 47.84 mu M for Q(24) and 294.9 +/- 66.7 mu g g(-1) for skin retention. Compounds 13 and 14 gave Q(24) values of 274.44 +/- 50.90 and 220.21 +/- 59.63 mu M and skin retention values of 226.5 +/- 51.8 and 259.0 +/- 62.2 mu g g(-1), respectively.

In a document, author is Ayers, Sloan, introduce the new discover.

Over-alkylation side products are common in the alkylation of amines by substitution. In the synthesis of the novel HIV Maturation inhibitor BMS-955176, two over-alkylation byproducts were routinely observed at the penultimate synthetic step, in which a thiomorpholine dioxide side chain was added to the core molecule by alkylation of a primary amine. These two byproducts had drastically different HPLC relative retention times, despite both containing only one additional side chain. Adding complexity to the challenge of solving their structures was the proclivity of the two byproducts to interconvert. Positive- and negative-ion HRMS, as well as isolation and 1D and 2D NMR were utilized to determine their structures. These byproducts were additionally problematic in that they led to daughter impurities at the API step. (C) 2018 Elsevier Ltd. All rights reserved.

Now introduce a scientific discovery about this category, Electric Literature of 766-97-2.

Complexation of the symmetric cyclic diamine piperazine (1,4-diazacyclohexane) has been examined in dry dimethyl formamide by spectrophotometric titrations (with Cu2+, Ni2+) to define formation constants, and by stopped-flow kinetics to define the complexation rates and reaction pathway. Initial formation of a rarely observed eta(1)-piperazine intermediate occurs in a rapid second-order reactions. This intermediate then undergoes two competing reactions: formation of (chelated) eta(2)-piperazine (ML) or the formation of (bridging) mu-piperazine (in M2L and M2L3, speciation depending on relative concentrations). Protonation constants and formation constants for complexation in water of N-ethylpiperazine and thiomorpholine (1-aza-4-thiocyclohexane, tm) have been determined by potentiometric titration; 1:1 complexes with first-row M2+ display a log K from similar to 4 to 6, with speciation that suggests chelation of the heterocycles may be involved. Complexation of thiomorpholine has been further probed by the synthesis of Pd-II complexes. The N-monodentate coordination mode has been confirmed in trans-[Pd(tm)(2)Br-2] by an X-ray crystal structure. Complexation of N-(2-aminoethyl)piperazine to Cu-II as a bidentate ligand involving the primary and tertiary amines is also defined by an X-ray crystal structure.

In a article, author is Rodriguez-Lozada, Josue, introduce new discover of the category.

We have previously reported the synthesis, in vitro and in silico activities of new GABA analogues as inhibitors of the GABA-AT enzyme from Pseudomonas fluorescens, where the nitrogen atom at the gamma-position is embedded in heterocyclic scaffolds. With the goal of finding more potent inhibitors, we now report the synthesis of a new set of GABA analogues with a broader variation of heterocyclic scaffolds at the gamma-position such as thiazolidines, methyl-substituted piperidines, morpholine and thiomorpholine and determined their inhibitory potential over the GABA-AT enzyme from Pseudomonas fluorescens. These structural modifications led to compound 9b which showed a 73% inhibition against this enzyme. In vivo studies with PTZ-induced seizures on male CD1 mice show that compound 9b has a neuroprotective effect at a 0.50 mmole/kg dose. A QSAR study was carried out to find the molecular descriptors associated with the structural changes in the GABA scaffold to explain their inhibitory activity against GABA-AT. Employing 3D molecular descriptors allowed us to propose the GABA analogues enantiomeric active form. To evaluate the interaction with Pseudomonas fluorescens and human GABA-AT by molecular docking, the constructions of homology models was carried out. From these calculations, 9b showed a strong interaction with both GABA-AT enzymes in agreement with experimental results and the QSAR model, which indicates that bulky ligands tend to be the better inhibitors especially those with a sulfur atom on their structure.

While the job of a research scientist varies, most chemistry careers in research are based in laboratories, where research is conducted by teams following scientific methods and standards., Safety of 3-Nitrobenzaldehyde, 99-61-6, Name is 3-Nitrobenzaldehyde, molecular formula is C7H5NO3, belongs to thiomorpholine compound. In a document, author is Nwuche, Charles O., introduce the new discover.

The Antibiogram properties of 1-chloro-2-isocyanatoethane derivatives of thiomorpholine (CTC), piperazine (CPC) and morpholine (CMC) were evaluated by the approved agar well diffusion, the minimum inhibitory concentration (MIC) and in silico techniques. A total of fourteen microbial cultures consisting of ten bacteria and four yeast strains were used in the biological study while affinity of the compounds for DNA gyrase, a validated antibacterial drug target, was investigated by docking method. Results indicate that both thiomorpholine and piperazine had zero activity against the Gram negative organisms tested. With morpholine, similar result was obtained except that cultures of Escherichia coli (ATCC 15442) and Salmonella typhi (ATCC 6539) presented with weak sensitivity (7-8 mm) as shown by the inhibition zone diameter (IZD) measurement. The Gram positive organisms were more sensitive to morpholine than the other compounds. The highest IZD values of 15-18 mm were achieved except for Streptococcus pneumoniae (ATCC 49619) in which mobility of the compound stopped after 12 mm. S. pneumoniae was resistant to both thiomorpholine and piperazine. The yeast strains were not sensitive to any of the studied compounds investigated. The MIC tests evaluated against a reference antibiotic show that while morpholine was most active at 4 mu g.ml(-1) against both B. cereus ATCC (14579) and B. subtilis, the least active compound was thiomorpholine which inhibited S. aureus (ATCC 25923) at 64 mu g.ml(-1). The three compounds demonstrated high affinity for the target protein (DNA gyrase) ranging from -4.63 to -5.64 Kcal/mol and even showed better ligand efficiencies than three known antibiotics; chlorobiocin, ciprofloxacin and tetracycline. This study identified the studied compounds as potential antibiotic leads with acceptable physicochemical properties and gave the molecular basis for the observed interactions between the compounds and the target protein which can be harnessed in structural optimization process.

Fungal infection is a significant global health challenge in part due to the emergence of strains exhibiting resistance to nearly all classes of antifungals. This underscores the urgent need for the development of new antifungal agents that can circumvent this burgeoning problem. For the present research, a new selected set of pyrazolo[5,1-c][1,2,4]triazine derivatives 3a-g was prepared in high yield via the reaction of N1-(5-methylpyrazol-3-yl)hydrazonoyl chloride 1 with morpholine, thiomorpholine, 4-phenylpiperidine and N-(substituted)piperazines. The new compounds were evaluated for their in vitro antifungal and antibacterial activities. The screening revealed compounds with specific activity against pathogenic fungi, including Candida albicans, Candida auris, and Cryptococcus. Compound 3d, which incorporated N-phenylpiperazine moiety, exhibited the highest growth inhibition against C. albicans with a minimum inhibitory concentration of 16 mu g/mL. The compounds were superior to fluconazole in inhibiting Candida biofilm mass at sub-inhibitory concentration. Furthermore, the MTS assay confirmed that compounds 1 and 3d exhibited an excellent toxicity profile (not toxic, up to 256 mu g/mL, for mammalian cells). Collectively, the presented results demonstrate that the synthesized pyrazolo-triazines warrant further exploration for potential use as antifungal agents.

Thirteen thiomorpholine-bearing compounds were designed and synthesized as dipeptidyl peptidase IV (DPP-IV) inhibitors, with natural and non-natural L-amino acids as the starting materials. Their structures were characterized by H-1 NMR, C-13 NMR and HR-MS. The target compounds were screened for the DPP-IV inhibition, and the preliminary SAR result was obtained. Particularly, compounds 4c, 4d and 4f with good DPP-IV inhibition in vitro were further evaluated through a mouse oral glucose tolerance test (OGTT). The preliminary result showed the potential value for further studies on those thiomorpholine-bearing compounds as DPP-IV inhibitors. (C) 2011 Hai Hong Huang.
