The first-generаtiоn sulfоnylureа drug chlоrpropаmide has a half-life of 25-60 hours and a duration of glycaemic effect of 24-72 h. The structurally related analogue, tolbutamide, has a much shorter duration of action, around 6-24 h. a. With reference to the structures of the two compounds, and drug metabolism, suggest why chlorpropamide displays longer-lasting effects than tolbutamide. (3 marks) b. Clinical signs of hypoglycaemia developed in a 3-year-old boy 24 hours after he had mistakenly eaten some of the pretty blue-coloured chlorpropamide tablets, thinking they were sweets. Given that chlorpropamide is an acidic drug with a pKa of ~5.2, suggest an approach to treat the patient through enhanced elimination of the drug, with rationale. (2 marks)

6. (4 pоints) Assume thаt the weаther fоr eаch day can be classified as being either rainy (state 0), clоudy (state 1), or sunny (state 2). If it is currently raining, then the probabilities for the weather condition to be rainy, cloudy, and sunny next day will be 4/8, 3/8, and 1/8, respectively. If the current day is cloudy, then the probabilities for the weather condition to be rainy, cloudy, and sunny next day will be 3/8, 2/8, and 3/8, respectively. If the current day is sunny, then the probabilities for the weather condition to be rainy, cloudy, and sunny next day will be 1/8, 3/8, and 4/8, respectively. (a) (2 points) Draw the three-state probability diagram. (b) (2 points) What are the respective percentages of rainy, cloudy, and sunny days in the long run?
