Abstract
We have developed a robust quantitative structure-activity relationship (QSAR) model employing a dataset of 98 heterocycle compounds to identify structural features responsible for BACE1 (beta-secretase 1) enzyme inhibition. We have used only 2D descriptors for model development purpose thus avoiding the conformational complications arising due to 3D geometry considerations. Following the strict Organization for Economic Co-operation and Development (OECD) guidelines, we have developed models using stepwise regression analysis followed by the best subset selection, while the final model was developed by partial least squares regression technique. The model was validated using various internationally accepted stringent validation parameters. From the insights obtained from the developed model, we have concluded that heteroatoms (nitrogen, oxygen, etc.) present within to an aromatic nucleus and the structural features such as hydrophobic, ring aromatic and hydrogen bond acceptor/donor are responsible for the enhancement of the BACE1 enzyme inhibitory activity. Moreover, we have performed the pharmacophore modelling to unveil the structural requirements for the inhibitory activity against the BACE1 enzyme. Furthermore, molecular docking studies were carried out to understand the molecular interactions involved in binding, and the results are then correlated with the requisite structural features obtained from the QSAR and pharmacophore models.

Abstract
AbstractA series of novel 6-(sec-butyl)-3-methyl-1-(substituted phenyl)-5,6- dihydropyrrolo[3,4-c]pyrazol-4-(1H)ones 5a–h were synthesized using L-isoleucine methyl ester hydrochloride as the starting material. Their structures were characterized by 1H NMR, FT-IR, EI-MS and elemental analysis. Compound 5f was further analyzed by single-crystal X-ray diffraction. The bioassay results indicate that most of the compounds exhibit inhibitory activity against four plant pathogenic fungi Fusarium graminearum, Botrytis cinerea, Rhizoctonia cerealis and Colletotrichumcapsici.

Abstract
Tetramic acid derivatives are an important class of nitrogen heterocycles with a pyrrolidine-2,4-dione core as a key structural motif. From the sponge-derived fungus Beauveria bassiana, a new equisetin-like tetramic acid derivative, beauversetin (1), was isolated. The sea weed-derived fungus Microdiplodia sp. produced the tetramic acid derivative 2 (Sch210972) which was shown to inhibit human leucocyte elastase (HLE) with an IC50 of 1.04 μg mL−1.

Abstract
Nodulisporacid A (1) was isolated from a marine-derived fungus Nodulisporium sp. CRIF1, while vermelhotin (5) was obtained from an unidentified fungus CRI247-01 (a member of the Order Pleosporales). Both 1 and 5 occurred as equilibrium E/Z mixtures. Ester derivatives (2 and 3) and vermelhotin (5) showed cytotoxic activity against eleven cancer cell lines. Nodulisporacid A (1) and vermelhotin (5) exhibited moderate antiplasmodial activity.

Abstract
Most gene mutations associated with Alzheimer's disease point to the metabolism of amyloid precursor protein as a potential cause. The beta- and gamma-secretases are two executioners of amyloid precursor protein processing resulting in amyloid-beta. Significant progress has been made in the selective inhibition of both proteases, regardless of structural information for gamma-secretase. Several peptidic and nonpeptidic leads were identified for both targets.
