BACKGROUND [0002] Disorders of lipid metabolism or dyslipidemias include various conditions characterized by abnormal concentrations of one or more lipids (i.e., cholesterol and triglycerides), and/or apolipoproteins (i.e., apolipoproteins A, B, C and E), and/or lipoproteins (i.e., the macromolecular complexes formed by the lipid and the apolipoprotein that allow lipids to circulate in blood, such as LDL, VLDL and IDL). Dyslipidemia is a major risk factor for cardiovascular disorders including coronary heart disease. Dyslipidemias were originally classified by Fredrickson according to the combination of alterations mentioned above. The Fredrickson classification includes 6 phenotypes (i.e., I, Ha, lib, III, IV and V) with the most common being the isolated hypercholesterolemia (or type Ha), which is usually accompanied by elevated concentrations of total and LDL cholesterol. A second common form of dyslipidemia is the mixed or combined hyperlipidemia or type lib and III of the Fredrickson classification. This dyslipidemia is often prevalent in patients with type 2 diabetes, obesity and the metabolic syndrome. [0003] The management of dyslipidemia is an important part of the National Cholesterol Education Program Adult Treatment Panel III guidelines. The reduction of low-density lipoprotein cholesterol as the primary target of treatment is recommended. Various lipid altering agents are considered first-line drugs for attaining this goal. However, monotherapy may not always be optimal for patients with significant combined or mixed dyslipidemias (e.g., elevated low-density lipoprotein cholesterol plus hypertriglyceridemia) or with concomitant conditions that increase the patient's level of risk (e.g., type 2 diabetes or the metabolic syndrome). Accordingly, combination drug therapy, which utilizes complementary mechanisms of action to alter levels of one or more lipoproteins may be useful. [0004] It would be desirable to develop an effective treatment for management of lipid related disorders using fibric acid and statin derivatives that can be administered alone or in combination with one or more lipid altering agents. Lipid altering agents encompass several classes of drugs that include HMG CoA reductase inhibitors (statins), fibric acid derivatives (fibrates), cholesterol-ester-transfer-protein ("CETP") inhibitors, squalene synthase inhibitors, microsomal-triglyceride-transfer-protein ("MTTP") inhibitors, cholesterol absorption inhibitors ("CAIs"), soluble guanylate cyclase modulators ("sGC modulators"), bile acid sequestrants, nicotinic acid, thyroid receptor agonists, liver X- receptor (LXR) modulators, antisense inhibitors of apoB-100 or C reactive protein, and probucol and derivatives thereof (e.g. AGI- 1067). These drugs differ with respect to mechanism of action and to the degree and type of lipid modulation. Thus, the indications for a particular drug are influenced by the underlying lipid abnormality. Monotherapy with statins, which competitively inhibit the intracellular rate-limiting enzyme for cholesterol biosynthesis, and bile acid sequestrants, which reduce terminal ileal bile acid absorption, primarily lower plasma low-density lipoprotein (LDL) cholesterol by enhancing hepatic LDL-receptor activity. Monotherapy with fibrates, which serve as ligands for peroxisome proliferator-activated receptor α, a transcription factor influencing gene expression in lipid metabolism, reduces plasma very-low-density lipoprotein (VLDL) cholesterol and triglycerides, and also increases high-density lipoprotein (HDL) cholesterol. SUMMARY [0005] Briefly, the present application discloses compositions of fibric acid and statin derivatives and their use in methods of prevention and/or treatment of various lipid related disorders, wherein the administration of such compositions is to a subject in need thereof. The application also discloses pharmaceutical formulations comprising fibric acid and statin derivatives alone or in combination with one or more lipid altering agents. [0006] In accordance with the above, the present application discloses methods to prevent and/or treat lipid related disorders such as dyslipidemia, hypercholesterolemia, hypertriglyceridemia, sitosterolemia, and fatty liver disease, by administering a therapeutically effective dose of at least one fibric acid or statin derivative described herein, alone or in combination with another therapeutic agent such as a lipid altering agent or a PDE inhibitor. [0007] In a first aspect, compounds represented by the structure of Formula I or II: (I) (H) wherein R1 is chosen from H and halogen; R2 is chosen from H, halogen, cycloalkyl substituted with from 1 to 3 halogens, 3 3 COR , and (CH2)mNHOR ; R3 is phenyl substituted with from one to three halogen groups; Z is chosen from O and (CH2)nO; X is chosen from direct bond, O, NH, and an amino acid residue; R4 is chosen from OH, NO, NO , an amino acid residue, a fϊbric acid residue, guanidine, tetrazolyl, agmatine, an amino-containing compound; lower alkyl terminating in ONO, (ONO )P, or guanidine; a resveratrol residue; and an imidazoline receptor agonist residue; wherein m, n, and p are independently chosen from 1 to 3; and R5 is chosen from a residue of a statin are provided herein. [0008] In certain embodiments, the compositions can include therapeutically effective amounts of the compounds represented by Formula (I), which include, but are not limited to, any of the compounds for which the synthesis is shown in Examples 1-35. In other embodiments, the compositions can include therapeutically effective amounts of the compounds represented by Formula (II), which include, but are not limited to, any of the compounds for which the synthesis is shown in Examples 36-1 15. In still other embodiments, the present disclosure provides compounds comprising a fϊbric acid or statin derivative in the form of a salt, wherein a fϊ bric acid or statin residue is a cation or anion, and another molecule is presented as a counterion to the fϊbric acid or statin residue. In some embodiments, the counterion includes, but is not limited to, a NOS substrate or an amino-tetrazole compound. Synthesis of particular fϊbric acid or statin derivative salt compounds is shown in Examples 116-139, although any fϊbric acid or statin compound can be used.
