CARBOHYDRATE-GLYCOLIPID CONJUGATE VACCINES

The present invention relates to the field of synthesizing and biologically evaluating of a novel class of carbohydrate-based vaccines. The new vaccines consist of a multi-modular structure which allows applying the vaccine to a whole variety of pathogenes. This method allows preparing vaccines against all pathogens expressing immunogenic carbohydrate antigens. As conjugation of antigenic carbohydrates to proteins is not required the conjugate vaccine is particularly heat stable. No refrigeration is required, a major drawback of protein-based vaccines.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 122709-21-1, and how the biochemistry of the body works.category: oxazolidine

A protein nanocarrier from charge-conversion polymer in response to endosomal pH

A new type of polyion complex (PIC) micelle was prepared from lysozyme and the block copolymer, PEG-pAsp(EDA-Cit), that can switch the charge from anionic to cationic at the endosomal pH. The charge-conversion was due to the degradation of the citraconic amide side chain at pH 5.5. This abrupt charge-conversion can make the PIC micelles promptly release the internal protein in response to the endosomal pH. This pH-sensitive charge-conversion polymer is promising for the future design of nanocarriers for early endosomal release. Copyright

Effects of antiepileptic drugs on GABA responses and on reduction of GABA responses by PTZ and DMCM on mouse neurons in cell culture

The mechanisms of action of antiepileptic drugs effective against generalized absence seizures (antiabsence AEDs) remain uncertain. Antiabsence AEDs are generally effective against seizures induced in experimental animals by pentylenetetrazol (PTZ) and methyl-6,7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate (DMCM), drugs which reduce GABAergic inhibition. Thus, antiabsence AEDs have been suggested to enhance GABAergic inhibition. We studied the effects of several AEDs on GABA responses recorded from mouse spinal cord neurons grown in primary dissociated cell culture. Four antiabsence AEDs were included: ethosuximide (ESM), dimethadione (DMO), sodium valproate (VPA), and diazepam (DZP). Two experimental AEDs, CGS 9896 and ZK 91296, with anticonvulsant action against PTZ- or DMCM-induced seizures were also included. Possible effects of the antiabsence and experimental AEDs on PTZ- and DMCM-induced inhibition of GABA responses were also evaluated. PTZ and DMCM reversibly reduced GABA responses in a concentration-dependent manner. PTZ completely inhibited GABA responses at 10 mM (IC50 of 1.1 mM), whereas DMCM-induced inhibition of GABA responses reached a plateau level of 39% of control values at 1 muM (IC50 of 33 nM). ESM (1,200 muM), DMO (6 mM), VPA (200 muM), CGS 9896 (2 muM), and ZK 91296 (2 muM) did not alter GABA responses. DZP enhanced GABA responses in a concentration-dependent manner. The inhibition of GABA responses produced by PTZ 1 mM was unaltered by ESM (600 muM), DMO (6 mM), CGS 9896 (1 muM), or ZK 91296 (1 muM). Coapplication of VPA (200 muM) and PTZ (1 mM) slightly enhanced the PTZ effect. DZP (>10 nM), however, reversed the PTZ-induced reduction of GABA responses. The DMCM (250 nM) inhibition of GABA responses was unaltered by ESM (600 muM), DMO (2 mM), or VPA (200 muM). CGS 9896 (2 muM) and ZK 91296 (2 muM), however, antagonized the DMCM effect. DZP (>10 nM) significantly reversed the DMCM-induced inhibition of GABA responses. The lack of effect of VPA, ESM, and DMO on postsynaptic GABA responses suggests that direct enhancement of postsynaptic GABA action is not a common mechanism of action of antiabsence AEDs. The AEDs DZP, CGS 9896, and ZK 91296 all reversed DMCM, but not PTZ, reduction of GABA responses, suggesting that these AEDs blocked DMCM seizures by acting at benzodiazepine receptors. However, since only DZP enhanced GABA responses, it is unclear how CGS 9896 and ZK 91296 blocked PTZ seizures.

Asymmetric Total Synthesis of (+)-(3E)-Pinnatifidenyne via Abnormally Regioselective Pd(0)-Catalyzed Endocyclization

The asymmetric total synthesis of the marine natural product (+)-(3E)-pinnatifidenyne was accomplished. The key features of the synthesis involve the construction of an eight-membered cyclic ether by the abnormally regioselective Pd(0)-catalyzed cyclization, the installation of a double bond in the oxocene skeleton by sequential in situ deconjugative isomerization, and the efficient introduction of the crucial chloride mediated by the substrate-controlled diastereoselective reduction.

Hydrative Aminoxylation of Ynamides: One Reaction, Two Mechanisms

Organic synthesis boasts a wide array of reactions involving either radical species or ionic intermediates. The combination of radical and polar species, however, has not been explored to a comparable extent. Herein we present the hydrative aminoxylation of ynamides, a reaction which can proceed by either a polar-radical crossover mechanism or through a rare cationic activation. Common to both processes is the versatility of the persistent radical TEMPO and its oxidised oxoammonium derivative TEMPO+. The unique mechanisms of these processes are elucidated experimentally and by in-depth DFT-calculations.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 497-25-6
