The present invention relates to a pharmaceutical cocktail and methods of cancer treatment. In particular, one such cocktail comprises a combination of effective amounts of a lactate transporter inhibitor, a carbonic anhydrase inhibitor, a sodium potassium chloride cofactor (NKCC) transporter inhibitor, a member of the hydroxycinnamate class of drugs or a derivative thereof, and/or an angiogenesis inhibitor, including a vascular endothelial growth factor (VEGF) inhibitor such as bevacizumab in combination with blood vessel occlusion. As most cancers in an untreated state uses both aerobic and anaerobic/glycolytic pathways treatments contemplated herein can affect both metabolic pathways.

The invention belongs to the field of anti-arteriosclerosis drugs, and particularly relates to application of a carbonic anhydrase inhibitor to preparation of the anti-arteriosclerosis drugs. The study finds for the first time that carbonic anhydrase 1 (CA1) is highly expressed in arteriosclerosis calcified tissue, and CA1 is related to vascular smooth muscle calcification and affects cell proliferation and apoptosis. Methazolamide, the inhibitor of CA1, can significantly reduce the progression of atherosclerosis and inhibit atherosclerotic inflammatory factors. The results suggest that calcification plays an important role in atherosclerosis, and CA1-dominated calcification promotes the course of the atherosclerosis. Methazolamide has a potential therapeutic effect on the atherosclerosisby inhibiting expression of CA1. The findings not only further explain the close relationship between the atherosclerosis and the calcification, but also explore the calcification mechanism of the atherosclerosis, and further prove that inhibition of the calcification is a key point in the treatment of the atherosclerosis. The application of the carbonic anhydrase inhibitor to the preparation of the anti-arteriosclerosis drugs provides new ideas for the treatment of the atherosclerosis.

The present invention provides an ophthalmic composition comprising a hyperbranched polymer. The ophthalmic compositions may also comprise carbonic anhydrase inhibitors, wherein the hyperbranched polymer increases the aqueous solubility of the carbonic anhydrase inhibitor, and increases corneal permeation of the active agent. The ophthalmic compositions may also comprise non-ionic surfactants, such as polysorbate, hydroxypropyl methyl cellulose or hydroxyethyl cellulose, and beta-blockers, such as carteolol, levobunolol, betaxolol, metipranolol, timolol or propranolol.

The invention discloses a thermosensitive cyclodextrin-based carbonic anhydrase inhibitor and a preparation method thereof. In the inhibitor, a natural small-molecule inhibitor with a sulfonamide group is modified onto thermosensitive cyclodextrin with temperature response, an inhibitory effect on carbonic anhydrase is achieved through the sulfonamide group, and the reversible regulation of the activity of carbonic anhydrase is achieved through the thermosensitive effect of an alkoxy ether chain. When temperature is below a phase-transition temperature, the alkoxy ether chain stretches, the sulfonamide group can have good supramolecular interaction with carbonic anhydrase, and thereby the activity of carbonic anhydrase is inhibited. When temperature is above the phase-transition temperature, because the alkoxy ether chain is dehydrated to collapse to generate powerful steric resistance, destroying the supramolecular interaction between the sulfonamide group and carbonic anhydrase, and thereby the activity of the enzyme recovers again. Moreover, compared with other carbonic anhydrase inhibitors, the thermosensitive cyclodextrin-based carbonic anhydrase inhibitor is lower in toxicity and wider in resource, thus having high application value in the field of biomedical materials.
