Abstract
The role of interleukin-8 (IL-8) and its receptor CXCR2 in inflammatory responses and tumor development and progression has been well documented. Our study aims to discover novel compounds as CXCR2 antagonists to block the IL-8 signaling pathway using an in silico drug design. Herein, a structure-based pharmacophore model was developed based on the crystal structure of inactive CXCR2 in a complex with an allosteric inhibitor. This model was validated and refined, followed by virtual screening with the ZINC15 database. Subsequent molecular docking allows for predicting the best pose of a ligand inside a receptor binding site. We found that the 35 top-ranked hits exhibited docking scores from -30.81 to -25.28 kJ/mol and better interaction potential comparing the reference inhibitor. Analysis of ADME and toxicity properties revealed the efficacy and safety of the selected seven compounds. To validate the stability of the protein-ligand complex structure MD simulations approach has also been performed and confirmed via the critical parameters. The MD results explained that the CXCR2 receptor bound with two best-proposed molecules, including ZINC77105530 and ZINC93176465, was quite stable states as observed from low RMSD, RMSF, Rg, SASA values, and high occupancy of the interaction types. Finally, our data identified that these compounds play as potential inhibitors of IL-8 signaling pathways with the MM/GBSA binding free energies of -41.77 ± 6.45 kcal/mol and -38.84 ± 6.16 kcal/mol, respectively.Communicated by Ramaswamy H.

Abstract
Background Emergence of cross-resistance to current anti-malarial drugs has led to an urgent need for identification of potential compounds with novel modes of action and anti-malarial activity against the resistant strains. One of the most promising therapeutic targets of anti-malarial agents related to food vacuole of malaria parasite is haemozoin, a product formed by the parasite through haemoglobin degradation. Methods With this in mind, this study developed two-dimensional-quantitative structure–activity relationships (QSAR) models of a series of 21 haemozoin inhibitors to explore the useful physicochemical parameters of the active compounds for estimation of anti-malarial activities. The 2D-QSAR model with good statistical quality using partial least square method was generated after removing the outliers. Results Five two-dimensional descriptors of the training set were selected: atom count (a_ICM); adjacency and distance matrix descriptor (GCUT_SLOGP_2: the third GCUT descriptor using atomic contribution to logP); average total charge sum (h_pavgQ) in pKa prediction (pH = 7); a very low negative partial charge, including aromatic carbons which have a heteroatom-substitution in “ortho” position (PEOE_VSA-0) and molecular descriptor (rsynth: estimating the synthesizability of molecules as the fraction of heavy atoms that can be traced back to starting material fragments resulting from retrosynthetic rules), respectively. The model suggests that the anti-malarial activity of haemozoin inhibitors increases with molecules that have higher average total charge sum in pKa prediction (pH = 7). QSAR model also highlights that the descriptor using atomic contribution to logP or the distance matrix descriptor (GCUT_SLOGP_2), and structural component of the molecules, including topological descriptors does make for better anti-malarial activity. Conclusions The model is capable of predicting the anti-malarial activities of anti-haemozoin compounds. In addition, the selected molecular descriptors in this QSAR model are helpful in designing more efficient compounds against the P. falciparum 3D7A strain.

Abstract
Heterogeneity of peripheral blood monocytes is characterized by specific patterns in the membrane expression of Fc gamma-receptor III (FcgammaRIII/CD16) and the lipopolysaccharide receptor (LPS receptor CD14), allowing discrimination of distinct subpopulations. The aim was to analyze the correlation of these phenotypic differences to the early interaction of freshly isolated monocytes with modified lipoproteins by the use of either enzymatically degraded low density lipoprotein (E-LDL), acetylated low density lipoprotein (ac-LDL), oxidized low density lipoprotein (ox-LDL), or native low density lipoprotein. Highest E-LDL binding was observed on CD14(high) CD16(+) monocytes as determined by flow cytometry, suggesting a selective interaction of E-LDL with distinct subpopulations of monocytes. E-LDL induced rapid foam cell formation both in predifferentiated monocyte-derived macrophages and, in contrast to ac-LDL or ox-LDL, also in freshly isolated peripheral blood monocytes. This was accompanied by upregulation of the 2 class B scavenger receptors CLA-1/SR-BI (CD36 and LIMPII Analogous-1/scavenger receptor type B class I) and CD36. Cellular binding and uptake of E-LDL was neither competed by ac-LDL nor the class A scavenger-receptor inhibitor polyinosinic acid but was partially inhibited by an excess of ox-LDL. In predifferentiated monocyte-derived macrophages, an anti-CD36 antibody inhibited cellular binding and uptake of E-LDL by approximately 20%, suggesting that recognition of these hydrolase-modified low density lipoprotein particles is mediated only in part by the class B scavenger receptor CD36.

Abstract
Adipophilin, a marker of lipid accumulation initially described in adipocytes, was recently shown to be induced in macrophage foam cells. We found that even freshly isolated blood monocytes express adipophilin and that the amount of adipophilin protein is variable in monocytes from different healthy individuals. However, the physiological expression of adipophilin does not correlate with the levels of free fatty acids, cholesterylesters or free cholesterol. Enzymatically modified low-density lipoprotein (E-LDL) induces rapid foam cell formation in monocytes and upregulates adipophilin mRNA and protein within 2 h of incubation. This rapid induction of adipophilin is accompanied by a significant increase of free fatty acids in monocytes incubated with E-LDL. Adipophilin facilitates the uptake of free fatty acids, and here we demonstrate that free fatty acids increase is related to the early upregulation of adipophilin expression in blood monocytes. Fatty acids are ligands for peroxisome proliferator-activated receptor-gamma (PPARgamma), and the upregulation of adipophilin mRNA by PPARgamma agonists like 15d-PGJ(2) and ciglitazone indicates that PPARgamma may mediate the induction of adipophilin expression in human blood monocytes.
