Abstract
In order to make novel breakthroughs in molecular salt studies of BCS class-IV antifungal medication bifonazole (BIF), a salification-driven strategy towards ameliorating attributes and aiding augment efficiency is raised. This strategy fully harnesses structural characters together attributes and benefits of caffeic acid (CAF) to concurrently enhance dissolvability and permeability of BIF by introducing the two ingredients into the identical molecular salt lattice through the salification reaction, which, coupled with the aroused potential activity of CAF significantly amplifies the antifungal efficacy of BIF. Guided by this route, the first BIF-organic molecular salt, BIF-CAF, is directionally designed and synthesized with satisfactorily structural characterizations and integrated theoretical and experimental explorations on the pharmaceutical properties. Single-crystal X-ray diffraction resolving confirms that there is a lipid-water amphiphilic sandwich structure constructed by robust charge-assistant hydrogen bonds in the salt crystal, endowing the molecular salt with the potential to enhance both dissolvability and permeability relative to the parent drug, which is validated by experimental evaluations. Remarkably, the comprehensive DFT-based theoretical investigations covering frontier molecular orbital, molecular electrostatic potential, Hirshfeld surface analysis, reduced density gradient, topology, sphericity and planarity analysis strongly support these observations, thereby allowing some positive relationships between macroscopic properties and microstructures of the molecular salt can be made. Intriguingly, the optimal properties, together with the stimulated activity of CAF markedly augment in vitro antifungal ability of the molecular salt, with magnifying inhibition zones and reducing minimum inhibitory concentrations. These findings fill in the gaps on researches of BIF-organic molecular salt, and adequately exemplify the feasibility and validity by integrating theoretical and experimental approaches to resolve BIF's problems via the salification-driven tactic.

Abstract
Aim: To explore how to transform cocrystals of the anticancer drug 5-fluorouracil (FL) with caffeic acid (CF; FL-CF-2H2O) into a nanoformulation, a self-assembly strategy of cocrystal-loaded micelles is proposed. Methods: Nanomicelles were assembled to deliver cocrystal FL-CF-2H2O with synergistic activity, and their in vitro/vivo properties were evaluated by combining theoretical and experimental methods. Result: More cocrystal was packed into the polymers due to the stronger interaction energy during micellar assembly, producing excellent cytotoxicity and pharmacokinetic behavior, especially synergistic abilities and long-term therapy. Conclusion: This case exemplifies the particular benefits of the self-assembly strategy of cocrystal-loaded micelles in keeping a delicate balance between long-term effects and high efficiency for FL, and offers a feasible technical scheme for cocrystal delivery agents for antitumor drugs.

Abstract
Thiol and aminothiol compounds are among the most efficient chemical radioprotectors. To increase their efficiency, we synthesized two new classes of thiol and aminothiol compounds derived from benzothiazole (T1, T2, AM1, AM2) and thiadiazole (T3, T4, AM3) structures. We examined them for their ability to scavenge free radicals (DPPH*, ABTS(*+), *OH). Thiol derivatives with a thiadiazole structure are the most active compounds scavenging DPPH* and ABTS(*+) free radicals, with an IC(50) of 0.053+/-0.006 and 0.023+/-0.002 mM, respectively, for the derivative T3. Moreover, compounds T1, T2, and T3 at 60 microM gave 83% protection against 2-deoxyribose degradation by *OH. The ability of these compounds to protect DNA against *OH produced by a Fenton reaction and gamma-irradiation (15 Gy)-induced strand breaks was also evaluated on pBR322 plasmid DNA. In both tests thiol derivatives were the most efficient compounds. Derivatives T2 and T3 totally inhibit DNA strand breaks at the concentration of 50 microM. The protection afforded by these derivatives was comparatively higher than that of the radioprotectors WR-2721 and WR-1065. Our data indicate that these two compounds are free radical scavengers and potential antioxidant agents. Finally, DFT and QSAR studies were performed to support the experimental observations.

Abstract
The clinical efficacy of nonsteroidal anti-inflammatory drugs has been related to ionization energies [Mehler and Gerhards, Int. J. Quantum Chem. 1989, 25, 205]. In this paper we employ modern quantum-chemical calculations to re-examine the statistical correlation between clinical efficacy and ionization energies. Ionization energies are computed by density functional theory, with and without Koopman's theorem, for a series of salicylic acids and phenols whose activities, or efficacy, are known. Using a regression analysis, we show that improving the treatment of electron correlation beyond previous studies enhances the statistical correlation between clinical activities and ionization energies.

Abstract
The peroxyl-radical-scavenging mechanism of some nonsteroidal anti-inflammatory drugs (NSAIDs), namely tolmetin, ketorolac, indomethacin, acemetacin, and oxaprozin, is clarified by combined density functional theory (DFT) calculations. It is revealed that H-atom-abstraction rather than electron transfer reaction is involved in the radical-scavenging process of these NSAIDs in polar aqueous solution. This seems contrary to the common viewpoint that the latter is predominant in polar media. The calculated results also show that H-atom at C(beta) or C(gamma) position is readily to be abstracted, and the lowest C-H bond dissociation enthalpy (BDE) can qualitatively account for the activity difference for the five NSAIDs.

Abstract
Induction of phase 2 enzymes is a major strategy in chemoprotection against cancer. Inducers belong to nine different chemical classes. In this study we found that a measure of the tendency of 30 plant phenylpropenoids and synthetic analogs to release electrons correlates linearly with their potency in inducing the activity of NAD(P)H:quinone reductase (NQO1), a prototypic phase 2 cancer-protective enzyme. The tendency to release electrons was determined by the energy of the highest occupied molecular orbital (E(HOMO)), calculated by simple quantum-mechanical methods. The correlations observed establish a clear conclusion: the smaller the absolute E(HOMO) of an agent, A, i.e., the lower its reduction potential, E(A*+/A), the stronger is its electron donor property and the greater its inducer potency. The finding of this redox ranking of the inducers demonstrates the possibility of controlling and predicting the genetic expression of an enzymatic defense against cancer by xenobiotics via one physicochemical parameter, the reduction potential, E(A*+/A).

Abstract
Sulindac is a sulfoxide prodrug that, in vivo, is converted to the metabolites sulindac sulfide and sulindac sulfone. It is therapeutically used as an anti-inflammatory and analgesic in the symptomatic treatment of acute and chronic rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis. In addition to its anti-inflammatory properties, sulindac and its metabolites have been shown to have an important role in the prevention of colonic carcinogenesis. Although the inhibition of prostaglandin synthesis constitutes the primary mechanism of action of sulindac, it is well known that reactive oxygen species (ROS) and reactive nitrogen species (RNS) are implicated in the pathophysiology of inflammation and cancer. Thus, the aim of this study was to evaluate the scavenging activity of sulindac and its sulfone and sulfide metabolites for an array of ROS (HO*, O2(*-), and HOCl) and RNS (*NO and ONOO-) using in vitro systems. The results we obtained demonstrate that the metabolism of sulindac increases its scavenging activity for all RNS and ROS studied, notably with regard to the scavenging of HOCl. These effects may strongly contribute to the anti-inflammatory and anticarcinogenic efficacy that has been shown for sulindac.

Abstract
A set of thirty five molecules of 1,3-diaryl-4,5,6,7-tetrahydro-2H-isoindoles endowed with selective COX-2 inhibitory activity was analyzed using comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA). Besides conventional steric and electrostatic fields, seven additional descriptors were incorporated to the CoMFA models. An improved CoMFA model (r(2)(cv)=0.536, r(2)(conv)=0.968, SEE=0.222, r(2)(pred)=0.6564) was obtained by taking into account the CMR as additional descriptor. This analysis provided useful information regarding the pharmacophoric requirements for COX-2 inhibitory activity. FlexX was used to find out the binding orientation of this new class of 1,3-diaryl isoindoles in the active site of COX-2. The contour maps produced by improved CoMFA model was superimposed onto the active site revealing a good correlation between the contour maps and the active site residue interactions.

Abstract
Experimental IC(50) data for 314 selective cyclooxygenase-2 (COX-2) inhibitors are used to develop quantitation and classification models as a potential screening mechanism for larger libraries of target compounds. Experimental log(IC(50)) values ranged from 0.23 to > or = 5.00. Numerical descriptors encoding solely topological information are calculated for all structures and are used as inputs for linear regression, computational neural network, and classification analysis routines. Evolutionary optimization algorithms are then used to search the descriptor space for information-rich subsets which minimize the rms error of a diverse training set of compounds. An eight-descriptor model was identified as a robust predictor of experimental log(IC(50)) values, producing a root-mean-square error of 0.625 log units for an external prediction set of inhibitors which took no part in model development. A k-nearest neighbor classification study of the data set discriminating between active and inactive members produced a nine-descriptor model able to accurately classify 83.3% of the prediction set compounds correctly.

Abstract
Using semi-empirical AM1 calculation and 6.31G* basis sets, we have calculated the energy of the highest-occupied molecular orbital (E(HOMO)) for anti-inflammatory 4,5-diarylpyrroles which have been shown to have inhibitory activity on cyclooxygenase COX-2, an inducible enzyme expressed during inflammation. We have found a correlation between the E(HOMO) of a molecule and its COX-2 inhibition. However, no correlation was observed between E(HOMO) and the inhibition efficiency of cyclooxygenase-1 (COX-1), the constitutively expressed enzyme, protective to the organism. This result suggests that the inhibitions of the two isoforms follow different molecular mechanisms.
