No, you cannot, but when your wife becomes a US citizen herself, she can file petition for her parents and her brother. Noting that your wife is probably several years away from becoming a US citizen, and instead of waiting for your wife to become a US citizen, both her parents and especially her brother should consider their own respective independent under which, they can attain legal residency in United States in their own right.
