Its molecular formula was determined as C 19H 2 4N 2O 6S on the basis of HRESIMS, implying nine degrees of unsaturation. Structure Elucidation of the New CompoundsĬompound 1 was obtained as colorless crystals. Details of the isolation, structure elucidation, and biological activity of compounds 1– 6 are reported herein.Ģ.1. All these compounds were examined for cytotoxic and antimicrobial activities. The structures of these compounds were determined by detailed analysis of the NMR and mass spectrometric data and compounds 1 and 3 were confirmed by single-crystal X-ray diffraction analysis. Further work on the remaining fractions of the fungus resulted in the isolation of five new sulfide diketopiperazine derivatives, namely, penicibrocazines A–E ( 1– 5) and one known analog ( 6) ( Figure 1). Very recently, six new cytotoxic bisthiodiketopiperazine derivatives, brocazines A–F, have been isolated from the culture extract of Penicillium brocae MA-231, an endophytic fungus obtained from the fresh tissue of the marine mangrove plant Avicennia marina. As part of our recently initiated program aimed at the discovery of bioactive secondary metabolites from marine-derived fungi, a series of structurally interesting and biologically active natural products has been described.

Actually, two more dollars would be great!” “I’m probably going to keep biking maybe until they drop down about 50 more cents. ![]() I’m like two miles from my juice bar,” he said. “Yeah, I’ve been exercising more, riding my bike. A lifestyle change he said is healthy for his body and wallet. Williams is the owner of Juice Life RVA, a fresh-pressed juice shop in Shockoe Bottom and has been riding his bike to and from the shop because of high gas prices. Making us make different decisions on how we would get to work and get to school, wherever we’re going,” Williams said. “I would say it’s definitely killing everyone’s budget. Still, on Tuesday the price of crude plummeted once again to below $100 below for the first time since May.Īt the Wawa on Arthur Ashe Boulevard in Richmond, Ryan Williams joked that the $25 cash he paid to get fuel might “get him to the light” right around the corner. The price for crude oil increased at the end of last week, a sign that comprises expect demand to pick back up. "But July is typically the heaviest month for demand as more Americans hit the road, so this trend of easing prices could be short-lived." About 80% of stations are now selling regular for under $5 a gallon," said Morgan Dean, AAA Mid-Atlantic spokesperson. "Domestic gasoline demand dipped recently, which took some of the pressure off of pump prices. The question for many drivers, who are still feeling the financial strain at the pump, is whether the price drop is a short-term blip or a longer-term trend. Fewer drivers fueled up over the past week, while the supply of gasoline in the U.S. Tuesday, the Virginia average was $4.59, and in Richmond, the average price was $4.57.ĪAA Mid Atlantic said classic supply-demand dynamics are driving the dip in prices, which remain near historically high levels. Nationally, the price per gallon sits at $4.80. In the Richmond/Metro the drop was even more pronounced, falling 13 cents per gallon since last week. ![]() The average price for a gallon of gas fell ten cents over the past week in Virginia, according to AAA Mid Atlantic. ![]()
