Studies on lower epidermal papillae, the site of storage of basmati rice aroma compounds in Pandanus amaryllifolius Roxb

Pandanus amaryllifolius Roxb. is the only species belonging to the family Pandanaceae that has fragrant leaves. In the higher plants, aroma compounds in leaves are stored in vacuoles and epidermal outgrowths like papillae, glandular hairs and trichomes. The lower epidermis of P. amaryllifolius has papillae as protrusions of lower epidermal cells. The papillae run parallel along the leaf length and are absent over the veins and midrib. The number of papillae varied from one to seven per cell. Papillae were also found surrounding the stomata forming a necklace-like structure. Quantitative analysis yielded 3.10 mg of 2-acetyl-1-pyrroline per kg of fresh leaves. Cell size, area and number of papillae were more in the clone of ‘Sawantwadi’ than in ‘Pune’.

Synthesis of Benzo[a]carbazoles and an Indolo[2,3-a]carbazole from 3-Aryltetramic Acids

A simple and flexible approach to 3-pyrrolin-2-one fused carbazoles is disclosed. The key step involves the BF3-mediated electrophilic substitution of indoles with N-alkyl-substituted 3-aryltetramic acids, which provides access to indole-substituted 3-pyrrolin-2-ones. Scholl-type oxidative cyclizations of these materials led to the formation of the corresponding 3-pyrrolin-2-one-fused benzo [a]carbazoles and indolo[2,3-a]carbazoles. This work represents the first synthesis of the benzo [a]pyrrolo[3,4-c]carbazol-3(8H)-one ring system, while the indolo[2,3-a]pyrrolo[3,4-c]carbazol-5-one ring system is found in a number of biologically active compounds including the protein kinase C (PKC) inhibitor, staurosporine.

Synthesis of the 26-Membered Core of Thiopeptide Natural Products by Scalable Thiazole-Forming Reactions of Cysteine Derivatives and Nitriles

The increased resistance of bacteria to clinical antibiotics is one of the major dilemmas facing human health and without solutions the problem will grow exponentially worse. Thiopeptide natural products have shown promising antibiotic activities and provide an opportunity for the development of a new class of antibiotics. Attempts to directly translate these compounds into human medicine have been limited due to poor physiochemical properties. The synthesis of the core structure of the 26-membered class of thiopeptide natural products is reported using chemistry that enables the synthesis of large quantities of synthetic intermediates and the common core structure. The use of cysteine/nitrile condensation reactions followed by oxidation to generate thiazoles has been key in enabling large academic scale reactions that in many instances avoided chromatography further aiding in accessing large amounts of key synthetic intermediates.

Solubility Measurement and Data Correlation of Thiabendazole in 12 Pure Organic Solvents from 283.15 to 323.15 K

The solubility of thiabendazole (TBZ) in 12 organic solvents (methanol, ethanol, n-propanol, isopropanol, n-butanol, isobutanol, acetone, butanone, methyl acetate, ethyl acetate, n-butyl acetate, and acetonitrile) was determined by the gravimetric method from 283.15 to 323.15 K. The solubility in all selected solvents increases with increasing temperature and in acetonitrile changes much greater than that in other solvents as temperature increases. The solubility of TBZ is higher in alcohol and ketone solvents than those in esters and nitriles. Besides, the solubility is mainly related to the solvent polarity and cohesive energy density in nonalcohols and influenced by the complicated combination of many factors in alcohols. Further, the Apelblat model, lambda h model, and NRTL model were used to correlate the solubility of TBZ. The relative deviation is less than 2.23% with the modified Apelblat equation, which shows better fitting performance compared with other two models.

Novel photodegradation of the antifungal antibiotic pyrrolnitrin in anhydrous and aqueous aprotic solvents

The UV irradiation of pyrrolnitrin (1a), which is an antibiotic clinically useful against dermatophytosis and possesses a unique 2-(pyrrol-3-yl)nitrobenzene moiety in the molecule, in an anhydrous aprotic solvent resulted in the exclusive formation of transient 7,4′-dichlorospiro[1,3-dihydrobenzo-(c)isoxazole-3,3′-pyrrolin-2′-one] (2a) via the intramolecular oxidation of the juxtaposed pyrrole ring by the triplet-excited nitro group. The irradiation in an aqueous aprotic solvent, however, allowed the concurrent occurrence of intramolecular cyclization by the singlet-excited nitro group in 1a and the hydroxylation at the 2-position of the pyrrole ring by water to afford 3,7-dichloro-8-hydroxy-8,8a-dihydropyrrolo[2,3-b]indol-2-one (3a), accompanied by the formation of 2a. Elongation of the irradiation time in these photoreactions caused a rapid consumption of the products, 2a and 3a, to give undetermined polar polymeric products. The present results indicate that the photodegradation of 1a is significantly influenced by the presence of water in the reaction media and by the nature of its excited state. Thus, the loss of the antifungal activities by the photosensitive antibiotic 1a was chemically proved.

Direct-type vinylogous Mukaiyama-Michael addition reactions involving pyrrolinone donors

The direct Mukaiyama-Michael addition of vinylogous tetramate donors to a number of different Michael acceptors has been easily executed, by employing the TMSOTf/Et3N Mixture as soft Lewis acid/base promoter agent. Richly functionalized, highly manipulable gamma-substituted pyrrolinone products were practically synthesized in acceptable to excellent yields, and with diastereoselectivities heavily relying upon the substituent at the nitrogen atom of the pyrrolinone donor.

Synthesis of Chiral, Densely Substituted Pyrrolidones via Phosphine-Catalyzed Cycloisomerization

Densely substituted chiral pyrrolidones are synthesized via phosphine-catalyzed cycloisomerization of enantioenriched beta-amino ynones, which are prepared in a single step using a highly enantioselective Zn-ProPhenol-catalyzed Mannich reaction. The exocyclic alkenes in the cyclization products provide versatile handles for further transformations and typically form with good E/Z selectivity. This cycloisomerization method can be performed in streamlined fashion, without purification of the intermediate Mannich adduct, and extends to anthranilic acid based scaffolds in addition to ProPhenol-derived Mannich adducts.

EPR spectroscopy detection of active oxygen and free radicals in thylakoids exposed to photoinhibition

High intensity illumination of thylakoids results in the well-characterized impairment of Photosystem Il electron transport (photoinhibition), followed by the degradation of the D1 reaction centre protein. The time course and features of photodamage are different in fully functional thylakoid membranes, when photoinhibition is invoked by impairment of Photosystem II acceptor side electron transport, and in thylakoids which are unable to oxidize water, when the damage is a consequence of inactivation of Photosystem II donor side. In the present study we followed the production of singlet oxygen and free radicals during both types of photoinhibition by EPR spectroscopy. Singlet oxygen was detected by following the formation of 2,2,6,6-tetramethylpiperidine-1-oxyl, a stable nitroxide radical yielded in the reaction of singlet oxygen with the sterically hindered amine 2,2,6,6-tetramethylpiperidine. Free radicals were detected as spin adducts of the spin trap 5,5-dimethyl-1-pyrrolin-N-oxide, and identified on the basis of hyperfine splitting constants of the EPR spectre. We found that (i) singlet oxygen, a non-radical form of active oxygen was detectable only in samples undergoing acceptor side induced photodamage. (ii) The acceptor side induced process was accompanied by the oxygen dependent production of carbon centred (alkyl or hydroxyalkyl) radicals, probably from the reaction of singlet oxygen with histidine residues. (iii) Donor side induced photoinhibition was dominated by hydroxyl radicals, which were produced in anaerobic samples, too. The production rate of these radicals, as well as D1 protein degradation, was dependent on the possibility of electron donation From manganese ions to Photosystem II. The marked distinction between the active oxygen forms produced in acceptor and donor side induced photoinhibition are in agreement with earlier reports on the different mechanism of these processes.
