Abstract
A new class of compounds formed by the linkage of -C(O)-NH- with pyridine and thiazole moieties was designed, synthesized, and characterized by various spectral approaches. The newly characterized compounds were evaluated for their antimicrobial as well as anti-inflammatory properties. The in vitro anti-inflammatory activity of these compounds was evaluated by denaturation of the bovine serum albumin method and showed inhibition in the range of IC50 values-46.29-100.60 μg/mL. Among all the tested compounds, compound 5l has the highest IC50 value and compound 5g has the least IC50 value. On the other hand, antimicrobial results revealed that compound 5j showed the lowest MIC values and compound 5a has the highest MIC values. Furthermore, molecular docking of the active compounds demonstrated a better docking score and interacted well with the target protein. Physicochemical parameters of the titled compounds were found suitable in the reference range only. The in silico molecular docking study revealed their COX-inhibitory action. Compound 5j emerged as a significant bioactive molecule among the synthesized analogues.

Abstract
Cyclooxygenase-1 (COX-1) is one isoform of COX, and it is a main target of nonsteroidal anti-inflammatory drugs (NSAIDs). It is important to develop efficient and selective COX-1 inhibitors. In this work, 12 classification models for 1530 cyclooxygenase-1 (COX-1) inhibitors were built by support vector machine (SVM), decision tree (DT) and random forest (RF) methods. The best classification model (model 1A) was built by SVM with MACCS fingerprints. The classification accuracies for the training and test sets were 99.67% and 97.39%, respectively. The Matthews correlation coefficient (MCC) of the test set was 0.94. We also divided the 1530 COX-1 inhibitors into nine subsets according to their different scaffolds using Kohonen's self-organizing map (SOM). In addition, six quantitative structure-activity relationship (QSAR) models for 181 COX-1 inhibitors whose IC50 were measured by enzyme immunoassay were built by multiple linear regression (MLR) and SVM. The best QSAR model (model 5A) was built by SVM with CORINA Symphony descriptors. The correlation coefficients of the training and test sets are 0.93 and 0.84, respectively. The models built in this study can be obtained from the authors.

Abstract
Melanogenesis plays an important role in the protection of skin against UV through production of melanin pigments, but abnormal accumulation of this pigment causes unaesthetic hyperpigmentation. Much effort is being made to develop effective depigmenting agents. Here, we show for the first time that a small library of mimosine dipeptide enantiomers (Mi-l/d-amino acid) inhibit the melanogenesis in B16F10 melanoma cells by down-regulating the cellular tyrosinase with little effect on their growth or viability. Two of them, Mi-d-Trp and Mi-d-Val, turned out to be the most potent inhibitors on melanin content and cellular tyrosinase in B16F10 melanoma cells. In addition, most of the mimosine dipeptides were more potent than mimosine for inhibiting cyclooxygenase 1 (COX-1) with IC50 of 18–26 μM. Among them, Mi-l-Val and Mi-l-Trp inhibited cyclooxygenase 2 (COX-2) more potently than indomethacin, with IC50 values of 22 and 19 μM, respectively. Taken together, our results suggest the possibility that mimosine dipeptides could be better candidates (than mimosine) for anti-melanogenic (skin hyperpigmentation treatment) and cyclooxygenase (COX) inhibition.

Abstract
OBJECTIVE The purpose of this study is to develop a quantitative structure-activity relationship (QSAR) model that can distinguish mutagenic from non-mutagenic species with alpha,beta-unsaturated carbonyl moiety using two endpoints for this activity - Ames test and mammalian cell gene mutation test - and also to gather information about the molecular features that most contribute to eliminate the mutagenic effects of these chemicals. METHODS Two data sets were used for modeling the two mutagenicity endpoints: (1) Ames test and (2) mammalian cells mutagenesis. The first one comprised 220 molecules, while the second one 48 substances, ranging from acrylates, methacrylates to alpha,beta-unsaturated carbonyl compounds. The QSAR models were developed by applying linear discriminant analysis (LDA) along with different sets of descriptors computed using the DRAGON software. RESULTS For both endpoints, there was a concordance of 89% in the prediction and 97% confidentiality by combining the three models for the Ames test mutagenicity. We have also identified several structural alerts to assist the design of new monomers. SIGNIFICANCE These individual models and especially their combination are attractive from the point of view of molecular modeling and could be used for the prediction and design of new monomers that do not pose a human health risk.

Abstract
Reaction of 4-arylmethylene-3,4-dihydro-[1]-benzothiepin-5(2H)-ones 1 with malononitrile in the appropriate alcohol in the presence of sodium afforded the 2-alkoxy-4-aryl-5,6-dihydro-[1]-benzothiepino[5,4-b]pyridine-3-carbonitriles 2 and not the isomeric forms [1]-benzothiepino[4,5-c]pyridine-1-carbonitriles 3 in high regioselective manner. The assumed structure of 2 was inferred through independent synthetic reaction of 3,4-dihydro-[1]-benzothiepin-5(2H)-one (4) with ylidenemalononitriles 5 under the same applied reaction conditions and confirmed by single crystal X-ray diffraction studies. However, reaction of 4 with arylidenecyanothioacetamides 6 in refluxing ethanol in the presence of basic catalyst (piperidine or morpholine) does not afford the expected 4-aryl-3-cyano-5,6-dihydro-[1]-benzothiepino[5,4-b]pyridine-2(1H)-thiones 7 and instead 4-aryl-3,5-dicyano-6-thioxo-2(1H)-pyridinethiolate monohydrates were isolated as piperidinium or morpholinium salts 8. On the other hand, reaction of 6 with cyanothioacetamide in the presence of a sufficient amount of basic catalyst yielded exclusively 2-amino-4-aryl-3,5-dicyano-2-pyridinethiolates as piperidinium or morpholinium salts 9. Meanwhile, 7 were prepared through the reaction of 1 with cyanothioacetamide in refluxing ethanol in the presence of a catalytic amount of piperidine. Anti-inflammatory activity screening of the prepared compounds using in vivo acute carrageenan-induced paw oedema in rats exhibited that all the tested compounds possess considerable activity. In addition, few synthesized derivatives reveal remarkable anti-inflammatory properties (2d, k, l) comparable with indomethacin which was used as a reference standard during the pharmacological activity screening studies.
