Process simulation is used for energetic evaluation of two novel strong bicarbonate forming solvents for post combustion CO2 capture, intended for coal- and natural gas based exhaust streams. An evaluation framework has been developed where process energy sinks are coupled to process energy balances based on the basic principles of a thermal heat engine. This procedure enables coupling of detailed solvent properties, such as reaction enthalpy, VLE, and kinetics, with the overall process operation, while accounting for the magnitude of the energy sinks in the process. The method identifies areas where there may be room for potential improvement, shows how the fundamental chemical properties of the solvents give rise to the overall capture potential, and highlights interdependencies between major energy sinks in the process. This framework is then used to clarify where heat is spent in the process for two novel solvent systems: activated 2-Piperidineethanol (2-PPE) and 1-(2-Hydroxyethyl)pyrrolidine (1-(2HE)PRLD). These novel solvents are compared with a base case of MEA and Cesar1. Activated 2-Piperidineethanol showed the best performance for the process setup evaluated in this work. The regenerative efficiency parameter for this solvent is 66% with an optimum specific reboiler duty of 2.78 MJ/kg CO2 removed; a 22% reduction compared to MEA in the coal case. Furthermore, the solvent seems to be sufficiently fast to be used in an industrial absorber and is a promising system for post combustion CO2 capture. This results in a power plant specific energy penalty for avoided CO2 of 0.27 kWhel/kg CO2. The evaluation framework can also identify the potential for additional energy improvements by economizing configurations for improved internal heat distribution.

After the CB1 receptor antagonist SR141716 (rimonabant) was previously reported to modulate food intake, CB1 antagonism has been considered as a new therapeutic target for the treatment of obesity. Several series of urea, carbamate, amide, sulfonamide and oxalamide derivatives based on 1-benzhydrylpiperazine scaffold were synthesized and tested for CB1 receptor binding affinity. The SAR studies to optimize the CB1 binding affinity led to the potent urea derivatives. After the additional SAR studies to optimize the substituents of diphenyl rings, the combination of 2-chlorophenyl and 4-chlorophenyl turned out to be the most potent scaffold. The CB2 binding affinity assay as well as functional assay was also conducted on these compounds. Herein we wish to introduce several novel CB1 antagonists with IC50 values less than 100 nM for the CB1 receptor binding.

A series of novel anthranilic diamide derivatives incorporating 1,3,4-oxadiazole or nitrogen-containing saturated heterocyclic moieties were synthesized, characterized, and evaluated for bacteriostatic activity against three phytopathogenic bacteria Xanthomonas oryzae pv. Oryzae (Xoo), Xanthomonas axonopodis pv. Citri (Xac), Ralstonia solanacearum (R. solanacearum). The preliminary biological results indicated that most compounds exhibit bacteriostatic activity against three phytopathogenic bacteria. Among these compounds, compounds 6g, 6f, and 6i displayed better antibacterial activity. In the test with concentration of 200 mug/mL, antibacterial activity of compound 6i and 6j was 96%. In particular, the bacteriostatic activity displayed by compound 6h against Xoo is similar to the one displayed by commercial drug bismerthiazol.

The p-type organic semiconductor (OSC) material tetrathieno[2,3-a:3?,2?-c:2?,3?-f:3?,2?-h]naphthalene (2TTN) and its alkyl-substituted derivatives Cn-2TTNs (n = 6, 8, and 10) have been developed based on the results of theoretical calculation-inspired investigation. A hole mobility for amorphous Cn-2TTNs (10-2-10-3 cm2 V-1 s-1) was accurately predicted by using a novel statistical method in which the geometric mean of the mobilities for many individual small molecular flocks in an amorphous solid was obtained by using molecular mechanical molecular dynamics simulations and quantum chemical calculations. The simulation also suggests that upon increasing the length of alkyl chains in Cn-2TTNs the mobilities become smaller as a consequence of a decrease in transfer integral values. Cn-2TTNs are synthesized in a microflow reactor through photoreactions of the corresponding precursors. Cn-2TTNs are then utilized in the fabrication of organic field-effect transistors (OFETs). Although spin-coated thin films of Cn-2TTNs are crystalline, the hole mobilities (10-2-10-3 cm2 V-1 s-1) of trial OFETs decrease upon elongation of the alkyl chains. This finding parallels the results of theoretical simulation. The simulation method for amorphous solids developed in this effort should become a useful tool in studies aimed at designing new OSC materials.

Camptothecin (CPT) derivatives are clinically effective poisons of DNA topoisomerase I (Top1) able to form a ternary complex with the Top1-DNA complex. The aim of this investigation was to examine the dynamic aspects of the ternary complex formation by means of site-directed spin labeling electron paramagnetic resonance (SDSL-EPR). Two semisynthetic CPT derivatives bearing the paramagnetic moiety were synthesized, and their biological activity was tested. A 22-mer DNA oligonucleotide sequence with high affinity cleavage site for Top1 was also synthesized. EPR experiments were carried out on modified CPT in the presence of DNA, of Top1, or of both. In the last case, a slow motion component in the EPR signal appeared, indicating the formation of the ternary complex. Deconvolution of the EPR spectrum allowed to obtain the relative drug amounts in the complex. It was also possible to demonstrate that the residence time of CPT “trapped” in the ternary complex is longer than hundreds of microseconds.
