Reactions of Aromatic Compounds @pdfstudymaterialss

🌟Chemistry In Everyday life - 🌟 Histamine,stimulates the secretion of pepsin. 🌟 Histamine is a potent vasodilator . lt contracts the smooth muscles in the bronchi. 🌟 Synthetic drugs brompheniramina ( Dimetapp) & terfenadine ( Seldane), act as antihistamines. 🌟 Antiallergic & antacid drugs work on different receptors. 🌟 Tranquilizer & analgesics are neurologically active drugs. 🌟 Noradrenaline plays a role in mood changes. 🌟 Chlordiazepoxide & meprobamate,are sutable for relieving tension. 🌟 Equanil is used in controlling depression & hypertension. 🌟 Barbiturates are hypnotic. 🌟 Analgesics reduce or abolish pain. 🌟 Aspirin & paracetamol are non - narcotic analgesics. 🌟 Aspirin inhibits the synthesis of prostaglandins. It use in prevention of heart attacks 🌟 Morphine is a narcotic analgesics. 🌟 The first effective anti bacterial agent prontosil. 🌟 Antibiotics have either cidal effect or a static effect on microbes. 🌟 Penicillin G has a narrow spectrum of. Ampicillin & Amoxicillin are synthetic modifications of penicillins. 🌟 In India, penicillin is manufactured at the Hindustan Antibiotics in Pimpri & in private sector industry. 🌟 Chloramphenicol, Vancomycin. & Ofloxacin are a broad spectrum antibiotics. 🌟 Antiseptics ( either kill or prevent the growth of microorganisms). 🌟 Dettol is a mixture of chloroxylenol & terpineol. 🌟 Iodine is a powerful antiseptic. 🌟 0.2% solution of phenol is an antiseptic while it's 1% solution is disinfectant. 🌟 Norethindrone is an synthetic progesterone derivative drug. 🌟 The estrogen derivative drug is ethynylestradiol. 🌟 Aspartame is the most successful artificial sweeteners. 🌟 Alitame is high potency sweeteners, although it is more stable than aspartame. 🌟 Sucralose is trichloro derivative of sucrose.It does not provide calories. 🌟 The two most familiar antioxidants are butylated hydroxy toluene (BHT) & butylated hydroxy anisole(BHA). @pdfstudymaterialss
