Organic acids, sugars, vitamin C, antioxidant capacity and phenolic compounds in fruits of white (<i>Morus alba</i> L.) and black (<i>Morus nigra</i> L.) mulberry genotypes
Mulberries (Morus spp) are historically grown in particular microclimatic regions in Eastern Anatolia, including Aras valley. In the valley, mulberries are one of the ancient crop and used for several purposes by local people. The aim of the present study was to first time evaluate organic acids, sugars, vitamin C, antioxidant capacity (TEAC assay, Trolox Equivalent Antioxidant Capacity). and phenolic compounds of the historical black and white mulberry genotypes growing Aras valley in Turkey. Results showed that, species and genotypes strongly influenced the chemical content and antioxidant capacity (p<0.05). Malic acid was the main organic acid in all genotypes and ranged from 1.130 to 3.040 g/100 g. Among sugars, fructose and glucose are predominant and were between 4.177 and 7.700 g/100g and 5.337 and 8.573 g/100g in all mulberry genotypes, respectively. The black mulberry genotypes showed remarkably higher antioxidant capacity determined by TEAC assay (10.167 to 14.400 µ mol TE/g) compared to white mulberry genotypes (6.170 to 9.273 µmol TE/g). Chlorogenic acid and rutin was the main phenolic compound

Polymorphic Signature of the Anti-inflammatory Activity of 2,2′- {[1,2-Phenylenebis(methylene)]bis(sulfanediyl)}bis(4,6- dimethylnicotinonitrile)
Weak noncovalent interactions are the basic forces in crystal engineering. Polymorphism in flexible molecules is very common, leading to the development of the crystals of same organic compounds with different medicinal and material properties. Crystallization of 2,2′- {[1,2-phenylenebis(methylene)]bis(sulfanediyl)}bis(4,6-dimethylnicotinonitrile)
by evaporation at room temperature from ethyl acetate and hexane and from methanol and ethyl acetate gave stable polymorphs 4a and 4b, respectively, while in acetic acid, it gave metastable polymorph 4c. The polymorphic behavior of the compound has been visualized through singlecrystal X-ray and Hirshfeld analysis. These polymorphs are
tested for anti-inflammatory activity via the complete Freund’s adjuvant-induced rat paw model, and compounds have exhibited moderate activities. Studies of docking in the catalytic site of cyclooxygenase-2 were used to identify potential anti-inflammatory lead compounds. These results suggest that the supramolecular aggregate structure, which is formed in solution, influences the solid state structure and the biological activity obtained upon crystallization

Genetic characterization of Iranian grapes (Vitis vinifera L.) and their relationships with Italian ecotypes
Grapevine (Vitis vinifera L.) is one of the oldest and most important fruit crops in the world. Iran is considered as one of the regions where grapevine plants have been used and taken into cultivation. In the present study, 12 simple sequence repeat (SSR) markers were used to evaluate the genetic diversity among Iranian grape cultivars and their relationships with Italian ones. The observed number of alleles (N) per locus varied from 6 to 20 and also the number of effective alleles (Ne) ranged from 1.34 to 2.00 among cultivars, indicating that the SSRs were highly informative. The polymorphism information content (PIC) values ranged from 0.49 to 0.87 and classified the six loci as highly informative markers (PIC > 0.70). The mean observed heterozygosity (Ho) was higher (0.85) than the mean expected heterozygosity (He) (0.43), demonstrating a random union of gametes in the population. Genetic similarity among cultivars ranged from 0.14 to 0.93, indicating high genetic variation among them. UPGMA and Bayesian clustering analyses revealed high genetic variation among studied cultivars and grouped them into two main clusters. The present findings might render striking information in breeding management strategies for genetic conservation and cultivar improvement
