A method for LCMS analysis and quantification of core metabolites (e.g. NADH/NAD, glycolysis, citrate cycle, etc.) was presented by the authors. I established their method on our own device, which worked well and only required the device-specific typical...
This work by Lafrance and co-work represents a very mild means to induce the decarboxylation of malonic acid derivatives with 1,1-carbonyldiimidazole (CDI). The reactive intermediate carbonyl imidazole moiety can be trapped with various nucleophiles in an...
Under nitrogen, 1,3-dichlorobenzene (1 mmol) and 1,3-diaminobenzene were dissolved in toluene (15 mL). Sodium-tert-butoxide (NaO-t-Bu) (3 mmol), Ni(cod)2 (0.1 mmol), and DPPF (0.3mmol) were added to the solution at room temperature. The reaction mixture was...
PNU-95666E (sumanirole) was reported to be a highly selective D2 receptor full agonist. It was originally developed for the treatment of Parkinson’s disease. An eight steps synthesis was developed for the scale up of enantiomerically pure (R)-sumanirole with...
I used this published synthetic method for making similar N-alkylated benzodiazepine molecules. The reaction was very reliable and good yielding in case of exact molecule but in my molecule, which was basically 1,4-benzodiazepine-2-one derivative, this...
Synthesized (3) and a compound similar to (4) but with protection on -OH groups.
For (3): Dissolving CBr4 in dichloromethane instead of pyridine gave a better yield as it involved using only one solvent throughout the reaction.
For (4): The formation...

After searching for an alternate protecting group for the protection of cis-dihydrocatechols, it was found that the butane-bisacetals...
This communication was outstanding in providing a comprehensive study of polyurea properties for:
1) Development of constitutive model for polyurea at high strain rate loading conditions
2) Study of polyurea behavior from a quasi-static to ultra high...
This paper does a thorough analysis of structure and property relationships. The analyiss is thorougouh and well backed up by data. I found the secion on deswollen materials particularly helpful and interesting.
This paper describes amazingly shortest synthesis for such a complex macrolide. Geldanamycin was synthesized in 20 steps using key steps such as Cu-catalyzed intramolecular amidation. I have used synthetic strategy to synthesize prodrug of geldanamycin with...
The experimental section was adequately detailed in procedure and results describing necessary DMA and MDSC data were given. No substantial differences were recorded while reproducing similar results.
The manuscript entitled “Regioselective Synthesis of Substituted Rubrenes” is nicely written and excellent piece of work. Manuscript describes a method to generate Rubrene derivatives using a Diels Alder reaction and Phenyl lithium addition as key steps....
Enhancement of carrier mobility due to a secondary structural arrangement resulting from the substituents in a porphyrin transistor was observed. OSCFETs based on two different porphyrin derivatives displayed excellent mobilities of 2.57 and 0.48 cm2 V-1 s-1....
The data in this paper is veryw ell laid out. The data is easily reproducable and the work is easy to follow.

t-Bu amine (50 mmol) and methyl acrylate (50 mmol) were dissolved in MeOH (10 mL) and stirred overnight under nitrogen. The secondary amine was isolated by Kugelrohr distillation after the MeOH had been removed by rotary evaporation. The purified material...
N-(4-carboxyphenyl) anthranilic acid (compound 31)
A mixture of 2-chlorobenzoic acid (1 mmol), 4-aminobenzoic acid (1 mmol), K2CO3 (2 mmol), Cu powder (0.009 mmol), and Cu2O (0.009 mmol) in 0.3 mL of 2-ethoxyethanol was refluxed at 130°C under inert...
Well written paper. The technique of using a removabile filler to direct pore size in a membrane is an innovative method and should be studied more.
Great paper highlighting the PK of propranolol. Went into ADME properties and expanding indications
