  • The discovery of new ligands with affinity and selectivity for the dopamine $D_2$ receptor subtypes is an important area in medicinal chemistry. The distribution of the $D_2$ receptors in the limbic areas of brain suggests that these receptors may be particularly an attractive target for the design of potential selective antipsychotic drugs without causing extrapyramidal side effects.

  • The quaternary ammonium cephalosporin derivatives were prepared with various pyridines substituted at the 3 or/and 4 position. Their in vitro antibacterial activities were determined and substituent effect on pyridine nucleus was studied. Preparation of substituted pyridines are also described.

  • The authors reviewed information about biorefining of biomass by using academic information databases. Feedstocks were classified into triglycerides biomass, sugar biomass, starchy biomass, lignocellulosic biomass, and organic waste biomass. Biorefinery is an integrated system converting biomass into biofuels and biochemicals by various physical, chemical, biological, and thermochemical technologies. This paper presented a comprehensive summaries of opportunities, recent trends and challenges of biorefinery. A brief overview of promising building blocks, their sources from biomass, and their derivatives were also provided. In conclusion, this paper demonstrated the feasibility of biorefinery producing biofuels and biochemicals from biomass.
