The present embodiment provides a compound represented by the formula (1):

Q-CHR.sub.2  (1)

(Q is a nitrogen-containing aliphatic group containing two or more tertiary nitrogens but no oxygen, and R is an aliphatic group containing a biodegradable group). From the compound in combination with other lipids such as a lipid capable of reducing aggregation, lipid particles can be formed. Further, the compound can be used for a pharmaceutical composition to deliver an activator into cells.

Described herein are novel γ- and δ-propargyl carboxylic acids and esters. The novel compositions are antagonists of CSE and may be used to modulate of the activity of the carotid body, therefore providing therapeutic benefits for sleep-related breathing disorders and related conditions.

In various embodiments a cancer treatment method is provided based on inhibition of proline catabolism. When combined with p53 restoration therapy and/or inhibition of glutaminase, the inhibition of proline catabolism results in a “synthetic lethal” and synergistic anticancer response. Novel suicide inhibitors that induce the degradation of proline dehydrogenase (PRODH) are also provided. Also provided is a method of assaying PRODH to identify responders/non-responders to inhibition of proline catabolism and/or glutaminase.
