Abstract
Background:
Quinolines are an important class of heterocyclic compounds possessing a
wide range of biological activities. Previously, we had identified Schiff bases of quinoline as potential
anti-inflammatory agents, thus the current work is the continuation of our previous study.
Objective:
In the current study, 3-, 5-, and 8-sulfonamide and 8-sulfonate derivatives of quinoline
(1-50) were synthesized and their anti-inflammatory potential was evaluated. These synthetic analogs
were evaluated for their anti-inflammatory activity via ROS (Reactive oxygen species) inhibitory
effect produced from phagocytes from human whole blood.
Methods:
The sulfonamide and sulfonate derivatives of quinoline were synthesized via treating 5-,
3-, 8-amino, and 8-hydroxy quinolines with different substituted sulfonyl chlorides in pyridine. The
synthetic molecules were characterized using various spectroscopic techniques and screened for
their anti-inflammatory potential.
Results:
Among the synthetic derivatives 1-50, six compounds showed good to moderate antiinflammatory
activity. Compounds 47 (IC50 = 2.9 ± 0.5 μg/mL), 36 (IC50 = 3.2 ± 0.2 μg/mL), and
24 (IC50 = 6.7 ± 0.3 μg/mL) exhibited enhanced activity as compared to the standard ibuprofen
(IC50 = 11.2 ± 1.9 μg/mL). Compounds 20 (IC50 = 25.5 ± 0.7 μg/mL), 50 (IC50 = 42.9 ± 5.6 μg/mL),
and 8 (IC50 = 53.9 ± 3.1 μg/mL) were moderately active, however, rest of the compounds were
found to be inactive.
Conclusion:
The sulfonamide and sulfonate derivatives of quinoline were found to have promising
anti-inflammatory activity. Further studies on the modification of these molecules may lead to the
discovery of new and potential anti-inflammatory agents.

Abstract
( Z)-5-(3,5-Difluoro-4-hydroxybenzylidene)-2,3-dimethyl-3,5-dihydro-4 H-imidazol-4-one (DFHBI) and its analogues are fluorogenic molecules that bind the Spinach aptamer (a small RNA molecule), which was selected for imaging RNA. They are extremely weakly fluorescent in liquid solvents. It had been hypothesized that photoisomerization is a very efficient nonradiative process of deactivation. We show, consistent with the results of other studies, that if the isomerization is impeded, the fluorescence signal is enhanced significantly. In addition, we provide a thorough characterization of the photophysical behavior of DFHBI and its derivatives, notably that of ( Z)-5-(3,5-difluoro-4-hydroxybenzylidene)-2-methyl-3-((perfluorophenyl)methyl)-3,5-dihydro-4 H-imidazol-4-one (PFP-DFHBI) in various solvent environments. Solvent-dependent studies were performed with various mixtures of solvents. The results suggest that hydrogen bonding or strong interactions of the solvents with the phenolic-OH group change the absorption band near 420-460 nm and the nature of emission near 430 and 500 nm through various degrees of stabilization and the transformation between the neutral and the anionic species at both ground and excited states. These observations are confirmed by using a methoxy-substituted molecule (( Z)-5-(4-methoxybenzylidene)-2,3-dimethyl-3,5-dihydro-4 H-imidazol-4-one), where the 420-460 nm band is absent in the presence of methanol and the spectra are similar to those of PFP-DFHBI in noninteracting solvents, such as acetonitrile and dichloromethane. Thus, in addition to the major role of photoisomerization as a nonradiative process of deactivation of the excited state, the fluorescence of DFHBI-type molecules is very sensitively dependent upon the pH of the medium as well as upon solvent-specific interactions, such as hydrogen-bonding ability and polarity.

Abstract
Buxidin (1) and E-Buxenone (2), steroidal alkaloids from Buxus hyrcana, are found to possess potent immunosuppressive properties. The activity was tested in vitro on oxidative burst, chemotaxis, T-cell proliferation, and cytokine production. Both compounds showed a significant immunomodulatory activity with clear suppressive effect on oxidative burst and chemotaxis in a dose-dependent manner. They also exhibited suppressive effect on the phytohemagglutinin-stimulated T-cell proliferation. The immunomodulatory activity was further confirmed by the suppression of IL-2 and IL-4 production. Furthermore, molecular docking studies were performed to investigate the binding mode of Buxidin (1) and E-Buxenone (2) with IL-2. Despite the structural differences between Buxidin (1) and E-Buxenone (2), docking results revealed that they adopt a similar binding pattern at the active site of the IL-2. A good agreement between practical and theoretic results indicates that the current docking study could provide an alternate tool for the structural optimization of recently identified ligand as more potent IL-2 inhibitors.

Abstract
The tyrosinase inhibitory potential of seventeen synthesized oxazolone derivatives has been evaluated and their structure-activity relationships developed in the present work. All the synthesized derivatives, 3-19, demonstrated excellent in vitro tyrosinase inhibitory properties having IC50 values in the range of 1.23+/-0.37-17.73+/-2.69 microM, whereas standard inhibitors l-mimosine and kojic acid have IC50 values 3.68+/-0.02 and 16.67+/-0.52 microM,, respectively. Compounds 4-8 having IC50 values 3.11+/-0.95, 3.51+/-0.25, 3.23+/-0.66, 1.23 +/- 0.37, and 2.15+/-0.75, respectively, were found to be very active members of the series, even better than both the standard inhibitors. However, compounds 3, 9-11, 13, 14, 16, 17, and 19 were found to be better than kojic acid but not l-mimosine. (2-Methyl-4-[E,2Z)-3-phenyl-2-propenyliden]-1,3-oxazol-5(4H)-one (7) bearing a cinnamyol residue at C-4 of oxazolone moiety and an IC50 = 1.23+/-0.37 microM was found to be the most active one among all tested compounds. These studies reveal that the substitution of functional group (s) at C-4 and C-2 positions plays a vital role in the activity of this series of compounds. It is concluded that compound 7 may act as a potential lead molecule to develop new drugs for the treatment of tyrosinase based disorders.
