Is it permissible to give a portion of Zakat to a sick and unemployed brother, knowing that he does not have many obligations and sometimes receives money from his parents?

It is permissible to give zakat to a brother if he does not possess enough to cover his basic needs (food, drink, clothing, housing, and medicine), and he is unable to earn a living, and he has no one to support him, because by doing so, he is considered poor and in debt. This act is more virtuous due to its nature of upholding kinship ties and charity.
